Just installed 1.2b 2002092804 on Windows XP SP1 here over 1.2a. This build is
unable to download files. Choosing Tools -> Download Manager does not open the
download manger. Attempting to download a file results in message "   
c:\docume~1\jlemay~2.NJM\locals~1\temp\<filename> could not be saved, because
the source file could not be read. Try again later, or contact the server
administrator." being displayed. Tried this on multiple websites and multiple
downloads. Thought download.com would be the easiest to remember for testing.

Reproducible: Always

Steps to Reproduce:
1. Go to a website
2. Click a link to download a file
3. Error popup

Actual Results:  
Error popup message window appeared. Browser continues to function fine except
for the no download issue.

Expected Results:  
Downloaded the file and prompted for a save location. Why is Mozilla using DOS
style representations for long file names (using the tilda) in a Windows XP Pro
SP1  machine running a Windows build?

i cannot seem to repro this using today's trunk (commercial) build
(2002.09.30.10). then again, i'm on win2k, if that makes a difference...
WFM win xp trunk build 2002093010, downloaded an exe from download.com and can
see download manager (also tools->download manager works as expected)
could this possibly be a mozilla-only issue?
I can download fine with Mozilla 2002092804-TRUNK on Win XP SP1. Is this a
Branch only problem?
WFM WinXP both using phoenix and mozilla from the exact same sources
(trunk 2002093011). I downloaded Winzip8.1.
for a period of time on friday there was some broken code in contentAreaUtils.js
having to do with an interface change.  it was fixed late friday night / early
saturday morning.  i'm not sure if that temporary bustage could explain these
bug report though.
I'm seeing the same problem here with 2002092908 & 2002093010, win2k sp3

I have the same problem under Win2k. I can't save webpages nor images like I
described in bug 171588 which now seams to be dublicate of this one. But I can
download files through links or through FTP access. :-)

I can reproduce the bug by using latest Phoenix trunk. :-(

On the latest 1.0 trunk it works.

I saw this error, fixed it by installating in fresh folders.
Old Folders had been created 16th of september.

I am always deinstalling mozilla before installing a new nightly,
but I´m using the same folder mozilla.org for installation.
I used an older nightly to install 20020929 into an folder created 26th of
september. I couldn´t download 20020930, so I used NS4.79 for download.
After installation, I wanted to download some other files, 
Downloadmanager came up, sometimes very lately, but I could specify file and
folder. After clicking start download, downloadmanager closed, but didn´t go to
taskbar. Exiting Mozilla by clicking top-right x also crashed mozilla,
with netscape-talkback coming up, since Netscape4.79 was running?

Then I deinstalled mozilla, renamed the mozilla.org-folder, so a fresh folder
was created whenm re-installing.
After installation download was working again.
The corrupted folder had been created 26th of September, with a then current
nightly. I hadn´t used this machine for about 4 months, so I decided to ctreate
a new folder.

But the folder from the 26th and todays folder are having same curiosity:
c:\mozilla.org\Mozilla\components\Netscape\MozillaTrunk
Re comment #17, Save Image also works fine on 20020927-TRUNK on WinXP SP1.

I mention this to verify that it indeed appears to be part of the same problem.

Ummm, I hate to suggest this, but comment #18 suggests that this might be
another COMPREG.DAT issue.
i just installed 2002093010 over 2002092908 (uninstalled first), and that didnt
help.

however, deleting the mozilla.org directory (not the plugins-directory) did.

now with 2002093010 and i can download (and save images) again! yeah!

jdoer: can you try and see if this 'procedure' helps you?
To Comment 19 : 
David, yes I localized the same effect. Unitil 20020927 it worked under W2k SP3,
too.
How about "COMPREG.DAT"? I normaly clear uninstall die program directory but
leave this file in there. What did you mean with "another" problem with this
file? I'll try it removing that file... I'll be back! ;-)
Deleting the mozilla.org->mozilla folder (except plugins) and re-installing
2002093010 solved the problems here.  I did un-install before installing
2002092908, this is where I first saw the problem.  I did NOT uninstall between
2002092908 & 2002093010 initially, and the problem remained, only deleting the
mozilla folder and re-installing 2002093010 solved the problem.  I did NOT try
installing 2002092908 into a clean folder.
Uninstalling the 093010 build, then deleting compreg.dat, and then reinstalling
the same build did the trick here.

Probably the broken code mentioned in comment 13 corrupted this file?

Works for me now.
*** Bug 171784 has been marked as a duplicate of this bug. ***
So, back after checking this thing... I uninstalled Mozilla 1.2 trunk. Removed
the chrome, defaults directory and in the components directory the Netscape
directory and the COMPREG.DAT file. Finaly I made a new clean installation and
voila! It works! :D

Nice new plugin:about page! :D

Just to clarify the last few comments based on my testing.

I uninstalled 20020927 (using Mozilla/Win uninstall process), then installed
20020930. I couldn't download anything. I exited Mozilla, then deleted
COMPREG.DAT. After restarting 20020930, I can now download files.

I thought this COMPREG.DAT problem was fixed in Bug #162593 ?
QA Contact: sairuh → nobody
ah, brilliant.

minor problem, suppose you have:
mozilla.exe dated monday
you run mozilla on wednesday, it touches compreg.dat (now dated wednesday)
you get a new mozilla.exe, but it's only dated tuesday.

you run mozilla, it checks, and compreg.dat is newer than it is. What's a poor
mozilla to do?

No one here has mentioned using the .zip builds, in fact no one here has
mentioned '.zip' or 'installer', so I need two people to comment in this bug as
to which they were using.  And then I need at most one person to comment if they
were using the other type.

My comments in comment #27 are based on using the Win32 installer as downloaded
from Mozilla.
my comment #20 is based on the installer.exe from the lastest-builds directory.

Re: comment #28
my installations in comment #18 are based on installer.exe, since I don´t know,
how a zip-installation affects the windows registry or other folders.

Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.2b) Gecko/20020930
OS: Windows Version 4.10.1998 (Win98 SP1)

Would be nice to have a doc somewhere that explains what files are affected by
an installation, and what that files are used for.
I´m a programmer, but not a mozilla programmer, so bugzilla is my means to get
some information about mozilla. The sourcecode is too big to start with.
Simply deleting compreg.dat when Mozilla is not running will cure the problems.

my guess is that poor mozilla should check a version number in compreg.dat (the
buildID?), since it cannot rely on the file-timestamp.


I used the complete installer.exe from latest trunk.
>my guess is that poor mozilla should check a version number in compreg.dat (the

that's useless. you can add new components to mozilla. (even non-developers,
think installing an xpi)

why can't it rely on the timestamp?
As far as I know, it relies on the file the installer creates to tell it to
autoregister. For some reason the file is not created, autoreg doesn't notice it
or autoreg doesn't work in some situations when updating an existing compreg.dat.
re comment 38:

see the scenario timeless sketched? 

and, if you 
1) install additional xpi's, 
2) uninstall mozilla before upgrading as usually suggested instead of just
installing over the old version when encountering errors,

then the xpi's aren't "installed" anymore. at least, that's been my experience
for the last few months.
*** Bug 171871 has been marked as a duplicate of this bug. ***
fwiw the zip package forces compreg to update (this is a relatively recent
change), which is why the question (and the answer [installer]) was so important
and interesting.

I'm not going to tell people to switch to the zip builds, but until someone
complains about this problem in the zip builds I'm going to take a bit of credit
for not hearing about this problem from people who use them :).

timeless,

Do you think that Bug #162593 should be reopened to address the root cause of
this bug? (And thus, this become a dup of 162593).
not sure if this is the same bug or not, but it may be related to
http://bugzilla.mozilla.org/show_bug.cgi?id=172249.
I have attached an ethereal packet capture file (is this any use?)

trying to download the nightly build does give a dialog box as mentioned in the
original bug report post.
Download at 2nd try -- Build ID 2002100218 full installer.exe Win98 SP1

started download of phoenix nightly, Downloadmanager came up, went to tray as I
was surfing. When I looked at Downloadmanager, it had finished with 1 kb.
I didn´t find the file in the directory, nor via search disk for all files since
last day.

started download again, looked at another tab, looked at downloadmanager
download had started, there was an entry with 0 kb in my download directory,
now finished with 7.624 kb

What if read here about installing, isn´t the stuff written in the release
notes. I used to download, going offline, then deinstall the old and install the
new installer.exe. From reading here, I got the impression, using zip-files
might be better, so I installed a zip-file over an installer version,
but the installerversion was in mozilla.org/Mozilla, the zip-version created in
mozilla.org/bin. Wouldn´t that give problems with registered files?
So I deinstalled Mozilla, and deleted the Mozilla directory, including plugins
and mozilla/bin, my zip-version.

I have tried uninstalling, and reinstalling.  That works, but then the same
errors occur a few hours later.  I was using the 20020930 installer as the last
one.  Error was still present.  I just d/led teh 20021004 installer, installed
over old one, and error still persists.  I'm going to try to uninstall and
reinstall to see if that helps.  Would be nice if a simple "update" could be
performed instead of an entire uninstall/reinstall.

successfully (9.72 Kb/sec - 615247 bytes)

Note the "Successfully" part on the last item. This was done under the bugged
DL. It "saved" it somewhere, but a search for the file yeilded nothing.

(Note 1: shift-click on a link will pop up the save location box instead of the
error message, however it never saves it)

(Note 2: downloads seem to work without a problem when saving attachments from
Mail, however you have to right-click save as, normal double-click yeilds no
responce)
im not an expert but mozilla saves files to a temp directory under a randomly generated filename while it is downloading then when the file is done it copies the file to where you actually saved it and renames it from the random filename to the filename you gave it when you saved the file. dont ask me why it does this... if you look at the error message you will see this.

"c:\docume~1\jlemay~2.NJM\locals~1\temp\<filename> could not be saved, because
the source file could not be read. Try again later, or contact the server
administrator."

is this bug going to be fixed or is the priority low now that there is a workaround?
Hi, I am pretty sure I solved this problem for myself by
1. Creating a new profile. (downloads immediately worked).
2. Copy in the downloads.rdf file from the new profile in to your existing profile.
3. Now the original profile can download both using ftp and http
4. Copy back in the original downloads.rdf... downloads now work with the
original downloads.rdf.
(my original downloads.rdf is 74,488 bytes. ?size limit)
Can someone who is currently experiencing this try this ?
Experienced this problem in Win98 ver 4.10.1998 (original) on nightlies from
10/13 and 10/14/2002. Besides inability to save files, I also noted that it
would not fire helpers (for midi, wav files). No indications in that case, just
a quick blink of the throbber.

I am verifying this with 2002092804 (1.2b).  In my mind, this is a pretty big bug.

I uninstalled 1.2a before installing 1.2b, but I didn't remove my profile...so
this is possibly something to do with the old profile?

I'll try the workaround from comment 66 to see if that solves it and will report
back.
Ok...after uninstalling everything and doing a complete registry search to
remove everything Mozilla-ish, and deleting my profile, then reinstalling Moz
1.2b, and then importing back my old profile, it seems to work just fine again.

Something else odd was that before I did all this, I could not get Download
Manager to open at all, even if I created a completely new profile.  Going to
Tools>Download Manager had no effect.

Anyhow...definitely something strange going on here.

I see this problem at work (Win2K-SP2) with the latest, 2002-10-17-04, nightly
(and for a while before that) but I've never seen it at home (WinXP) using
mainly CVS builds, but also not with the 2002-10-08-08 nightly (installed due
to, now fixed, Mail/News bugs).

On my home machine I don't have a COMPREG.DAT file but I've just dialled into
work and found that I do there - I'll delete it tomorrow and hopefully this will
be fixed :-)

Question? How come I don't have a COMPREG.DAT file on my home machine? What does
it do? It doesn't appear to be essential.

Deleting compreg.dat and restarting fixed the problem for me--I'd been seeing
this in the nightlies for a while and had gone back to 1.2a to fix it.

This should be added to the release notes as soon as possible, if it isn't
possible to fix it quickly.
Hmmm... this is second or event third bug i meet with, when deleting compreg.dat
helps.
Also i notice, that Mozilla after start, if no suh file found, build it one more.
Basing on this, i think that fast fix, is to add to installer function which
will delete compreg.dat if old one found.

With 1.2 beta on Windows 2000, deleting compreg.dat and restarting makes
downloads work for me.
The happened to me after I installed 1.2b-installer on a MSWin98 system. 
Strangely, it not only affected the main copy of Mozilla, but also all of the
other versions around (I normally keep three back available, most as
talkback.zip rather than installer.exe).  This was resolved by uninstalling 1.2b
and reverting to 1.1.  Then 200209284 started working (and I assume the rest).

Previous to that I determined that Netscape 4.7 was unaffected (so I knew it
wasn't a firewall stopping me).

This happened on several different sites.
Happened with 1.2b for me as well on XP SP1.  Deleted compreg.dat and restarted
as stated above.  Works good now.  
Win2k SP 3. Deleted compreg.dat, which seems to have removed spell checking, but
downloads now work again

Took recommended steps (compreg.dat).  Worksforme.

Sorry about another dup, but why didn't this bug (or the billions of duplicates)
show up when I searched for any browser bug with the word "download"?

Maybe not an appropriate question for this forum.  Taking myself off the CC
list.  Thanks!!
can someone put the fix for this in the release notes in big bold letters! :)

This bug also appears using Windows XP Pro and Beta Version 1.2b
David
Using 1.2b this just started with that version, not with 1.2a.  Then when I try
to go back to 1.2a it causes an error in a call not being found to one of the
dlls that is installed. the only way I could get this to go away was to install
one of this nightly build of 1.2b

Am using Windows 2000 pro with Mozilla build 200293004
Tried all the current solutions but am still having problems downloading nightly
builds. It seems that it's not an ftp problem but a code problem originating
from the "Compreg.dat" file. The only way, for now, that I can download any new
versions is using Netscape 4.79. Also FYI this seems to be a WINDOWS 32 problem
only since I do not have this problem when downloading other OS builds when
using my current Mozilla build.

It seems that there are a lot of dupes for this bug. I think it should be made a
critical problem. For some deleting or uninstalling all folders seems to work to
a point but when they try downloading a newer or latest nightly build the
problem returns. Deleting compreg.dat does not work either since when you try to
download another time a new compreg.dat file is replaced by a newer one. If
anyone out there has a clue please post a "REAL" solution to this problem.
Compreg.dat has caused many problems. So my feeling is that this file needs a
closer look. One would think, with all the "Experienced" programers using
Mozilla plus the orginators, they would have a sense of pride in making sure
this file does it proper function. Does anyone have suggestion as to how this
can be fixed not a worksforme solution.....?????

I've been experiencing this bug for a few days now. After the first time I
encountered it I shutdown the browser and received the following error message
which was also recorded in the Win2k system log:

Application popup: XPCOM:EventReceiver: Mozilla.exe - Application Error : The
instruction at "0x6190392e" referenced memory at "0x00000000". The memory could
not be "read".

I'm using Win2k SP3 and Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2b)

Hope this helps narrow down where the error is occuring..

Since upgrading to Mozilla 1.2b on Win98 I cannot download any files via the
browser, or 'save as link'. This worked fine in 1.1. The error message I get
when trying to download looks like this... "C:\WINDOWS\TEMP\n853f968.jpg could
not be saved, because the source file could not be read. Try again later or
contact the server administrator." Not sure why it thinks all downloads are .jpg
files, had to download the following NetTime program via MS-IE :[

clean up old component registry like before

i don't like how we just delete the component registry file.  This will break
any components which have been installed outside of the components directory 
(such as components existing in a GRE)

however, since this is what we have been doing and this patch will fix manyof
the bustages that are being reported, r=dougt.	Oh, and it doesn't hurt to
continue deleting the component.reg file.
Problem mirrored after migrating from 1.1 to 1.2b on XP Professional non SP1


This bug appeared when I changed the o/s so that a period appears in a directory
name in the pathname to the file location that cannot be read - causing the
download to abort. Since the v1.1 downloader has a problem with extra periods -
e.g. does not handle ../*.ps.z correctly - can someone check to see if that is
the source of the problem here also?

This endless parade of duplicates really might be avoided if this was added to
the release notes for 1.2b.  It is still not in there, in known problems, or
installation notes, even though there were other post-release additions to the
release notes:

http://www.mozilla.org/releases/mozilla1.2b/

In addition, this could be placed on the homepage near the download link.  Is
there some reason that the release notes just couldn't be updated?

Here's sample text, to go under "Known Problems" or "Installation notes" or "New
Additions to the Release Notes."  Just cut and paste.

<P>
 If you encounter the message "[filename] could not be saved, because the source

"i'd be

  I think most people probably did look for this in the release notes and on
Bugzilla.  The problem is that if you go to http://bugzilla.mozilla.org/ and
type in search terms in the provided form like "could not be saved," or "could
not be read" this bug simply does not show up.  Try it.  Give people some
credit.  Mozilla users usually aren't dummies.

   A fix or different defaults to the search may prevent such widespread
problems in the future.  Does anyone have a solution to this?

Given that his email address is timeless@something, how hard is it to guess

I think a lot of the dupes might come from the fact that nobody suspects this
bug to belong to the XPCOM registry component. When I posted my dupe I searched
the general browser and download manager components because I was experiencing
download problems.

Maybe add a feature to Bugzilla: "bug affects components" section in the bug
properties, a search in these components would bring up the bug even though it
is posted in a different component.
*** Bug 177483 has been marked as a duplicate of this bug. ***
1) I suspect the reason more people aren't finding this is that on the default
system search RESOLVED bugs are not returned.  See my comments on bug 176469.  I
also have no idea what the XPCOM registry is, and would certainly not have
thought to look there for this bug.

2) I see the note that a fix has been checked in.  It would be nice if someone
could post info on what was causing the problem.

- only one application can run (and works ok), any second one stucks, for xmple
  start browser -> no mail , no composer and vice versa
- only way to change apps is setting the start app in preferences
- deleting compreg.dat -> new one is created, no change
- with browser always one error in sidebar
  tries to download my bookmarks, never ending
- uninstall, install former version -> no success
- uninstall, del mozilla-dir, install -> no success 
- same things with boots in between -> no success

anyone some idea what to do now?

If you want to cut down on the number of dupes, test the searchability of the
bug, and how it looks to the normal bugzilla user.

I reopened bug 174941 (a dupe here), moved it to the component people search for
PAC problems, and pointed it here via a depends. Based on the other PAC dupes,
modified the summary so it should show up to the normal unhappy PAC user. 

People can now search for the bug, find the workaround, the post-fixed build
dates, and reference this bug as well.

Until we get another milestone, it is probably going to keep raining.

Removing block on Bug #163993, Bug #174941 & Bug #176454. I beleive that if a
bug has been fixed, then it can no longer block other bugs. Change back if you wish.

Sorry for spam for those people who don't care about these sort of things.

amazing how people keep reporting this, it's been at the top of the frequent
duplicates list for weeks now.
Seems my bug 162271 -> bug 160755 has nothing to do with this one after all.
If you find anyone filing a dupe of this who has got canconfirm or editbugs,
tell me and I'll fix that problem right away :-) 268 dupes? The laziness of some
people beggars belief...

FWIW: I download a nightly at least once a day.  (Sometimes the 04 and 08
builds.) I managed not to get hit with this bug originally, having already done
a clean install and deleting compreg.dat, and haven't experienced it since it
was fixed - until this morning.

I saw it when using 200212108 (under XP) to download the 2002121104 build via
FTP.  (The download manager came up, I clicked on Save, and I got the "source
file could not be read" message.)  Of course, I immediately exited Mozilla,
deleted compreg.dat, ran Mozilla again and all was good.  But there seems to
have been some regression here for some reason.  Hopefully it was just a glitch
(?) that others aren't seeing.
Jason,

It is a glitch. I'm using build 2002121104 and have been downloading all day
without any problems.

Sorry for spam, I would have sent this as private eMail, but I thought it was
important that everyone on the cc list gets an answer to Jason's question.

Oh, and also marking this bug as Verified.

I have just started receiving this error over the past day or two.

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.4b) Gecko/20030411
Build Id: 2003041108
OS: Windows 98se

I had downloaded several files without any problems and even today downloaded
two files without the error. Then when attempting to download from
ftp://ftp.dantz.com/pub/retro_60_pro_trial.exe got this error.

I have closed down Mozilla and renamed the COMPREG.DAT file and then restarted
Mozilla and tried downloading again and received the same error.

I have just rebuilt the system and therefore Mozilla is a fresh install (even
though I normally would uninstall and reboot before installing). However, my
profile has been restored from backup.

I will attempt to uninstall Mozilla and install the latest build (using another
browser to do the download).

BTW, I am using the exe install.
I do not know which is a quirk but the latest nightly build (2003041408) has
worked for downloads.

I have down two successful downloads. One being the earlier indicated link and
the other
(http://www.mirror.ac.uk/sites/ny1.mirror.openoffice.org/stable/1.1beta/OOo_1.1beta_Win32Intel_install.zip)


Renaming compreg.dat wfm. I was not experiencing any errors, the normal commdlg
appeared, just no file save. Tools, download manager yielded nothing. Download
manager was not enabled to begin with. This appeared with the install of 1.4a.

I noticed compreg.dat was not recreated. Any implications of this?
Several of my users are this site have experienced this issue. I have not be
able to draw any correlation between operating environment (software, OS
version, etc.). Deleting compreg.dat WFM. Any ideas why this is happening?

Nominating for 1.4 blocker. Not being able to download files is a pretty big
nasty... we must have regressed again. Clearly, the number of duplicates of this
bug tells us this is either not fixed or has regressed.

I was able to note that a number of the users affected by this bug were using
the AOL.com Mail interface and a javascript invoked download.
Flags: blocking1.4?
I've filled Bug 203689 about a similar behaviour (or better said exactly the
same). But that Bug appeared with Mozilla 1.3, at that time this bug was already
fixed.
Flags: blocking1.4?
So now people are removing flags without documenting or explaining? Asa, if
you're going to spend the time to remove a flag, why not do it the right way? If
there's something that the people on this bug list need to do to get this bug
reopenned, tell us what we're doing wrong.
clintonj@umkc.edu: this bug is fixed, therefore it can't block a release.
cbiesinger@web.de: This bug is NOT fixed, therefore it COULD be re-openned.
Whether or not it blocks a release is up to Asa.

If this is not the proper way to bring attention to a bug that has clearly
reappeared, what is?
ok. delete compreg.dat in mozilla\components, that should fix this bug.
if you had installed mozilla over a previous installation without using the
installer and you got problems, that is no bug.

if you did install mozilla over a previous release with the installer, you
should reopen this bug or file a new one, requesting blocking1.4 on a fixed bug
is not useful.
The case is the later. The problem developed after approximately two weeks of
use of 1.4b and does not affect all my users. My entire user base is WinXP. What
else might cause corruption of this file?

Could we modify Mozilla to better handle a corrupt component.reg?

I cannot reopen this bug. Someone with more permission must do it. This is
driving me crazy. I want to help by letting you guys know there's a problem. If
I file a new bug, it get's marked as duplicate. If I do everything I can to
bring attention to this one, I get ignored / chastized. Why is it so hard to let
someone know there's a bug? Also, I'll say it again: the number of duplicate
refiles of this bugs tells me that this is not an isolated occurance. This bug
is real and it IS happening.
is the compreg.dat file marked read-only?  can your users modify it?  Are they
installing any third party software that might change this file?
The file is not marked read-only. I suppose the users could play with it if they
knew how to open a file that doesn't have a .txt extention on the end. :) These
are not computer savey people.

And no, there's is no esoteric software installed that would go around modifing
.reg files.
I have run into this issue a couple times since the closing of this bug.  Each
time, I have been able to resolve it by opening Preferences then removing
everything (except text/html) from "Navigator -> Helper Applications". 
*** Bug 171981 has been marked as a duplicate of this bug. ***
Mozilla 1.5 on Windows XP.  Definitely not fixed.  I came across "...could not
be saved'.   I tried fixing that directory's permissions (fix is not permanent
on Windows XP).  I tried reinstalling, twice, with rebooting.  I tried deleting
the mozilla.org directory and my personal mozilla directory.  I do not have any
"helper applications" defined.  Still getting this error.

I notice several internet references this month, and I can't help but wonder if
the nearly daily security patches from microsoft we have to apply have broken
something.

Running the below version on windows xp home edition.

Mozilla 1.4
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624

Download worked fine until about 1 month ago, now I can't download anything. I
used this install for several months without problems until approximately
Christmas 2003.  I don't believe I updated windows recently, but I'm not sure
(there are other users on my pc that might have).

Deleting compreg.dat doesn't solve the problem.

Herb Desson 
Is it crashing? Are you getting the error message like the one described in the
description?

I am having this issue in Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.8b2) Gecko/20050316 Firefox/1.0+.
Have had it for pas tseveral nights.  Will work on a fresh install until I
restart the browser.
I have tried closing browser and deleting compreg.dat (from both the Program
Files and Application Settings folders).  No go.

Same here. After trying to solve it deleting compreg.dat, I made fresh Firefox
Install but still the same. Can't save files.
No longer blocks: majorbugs
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051118 SeaMonkey/1.5a

I am having this exact same problem with the SeaMonkey nightlies.  I cannot download anything with it!  In order to download SeaMonkey nightlies, I have to use FIrefox.

I would like to suggest that this issue be reopened.

Per comment 428 to comment 432: even though a similar problem and error message is experienced, it seems that the cause of your problem is very much different. The fact that deleting compreg.dat doesn't solve it points to that as well.

Since it is a different problem, I recommend that this bug remains "fixed" and someone that has experienced this problem instead opens a new bug report for this new problem. 

Please report the bug number of the new bug here.
