Same problem with Mozilla 1.6 on XP:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113

It started a couple weeks ago using a 6 month old version of Firebird. All yahoo
pages started coming up blank, with the "done" message on the status bar. I
upgraded to Moz 1.6 but still no fix. Seems as though something's changed at
yahoo. I can't find where at yahoo to complain.

I saw this for the last couple weeks with nightly builds of Firefox at but it doesn't seem to happen anymore.

Error log : blank page

I was facing the same problem as mentioned in this bug:

Using Mozilla 1.6 
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113
Tried upgrading to 1.7, but still the problem persists

From somewhere in net found that you can enable debug info on mozilla. Attached
is the log when the blank page comes.

I can't reproduce this with a recent trunk build of Mozilla 1.7 on WinXP or
Firefox 0.8 on WinXP or SuSe. Alan, can you reproduce this with a recent build?
If so, can you reproduce it with a new profile? Is there anything special about
your configuration?

I pulled down the lastest nightly builds for linux and winXP.  I tried both and
they both still fail.  I also tried the linux version with a new profile and the
same for winXP to rule out any personal settings.  So I still don't know what's
going on.  The only thing I can think of is it might be the corporate firewall?
 Any ideas?

unable to reproduce on red hat enterprise linux v. 3 and fedora core 2 test 2
with Mozilla 1.7 beta and a current nightly build. I visited all of the yahoo
products without problems. 

also tested windows XP with 1.7 beta and a current Firefox nightly build. No
problems there either.

I've now checked around on a handful of other machines including Red Hat Severn
beta, Fedora Core 1 and FC2.  I tested on a second winXP system and a win2K
system and wasn't able to reproduce the problem.  

If you're seeing this problem and upgrading to a newer build doesn't solve the
problem, can you try accessing yahoo sites with a new profile? You can create
and switch to a new profile in Mozilla from the Tools -> Switch Profile... menu
item or in Firefox by running firefox.exe -ProfileManager. 

If this problem is solved by a new profile, the next step would be to determine
which file in the profile was causing the problem. The first step might be to
check clearing the cache. After that it might be worth checking some of the
networking preferences to see if those who can reproduce all have something in
common there (Edit -> Preferences -> Advanced -> HTTP Networking or about:config
filtered to "network") 

Right now, without being able to reproduce this, I don't see how we're going to
make any progress fixing it. More information from anyone experiencing it would
be really helpful.

Now it working fine....

I am using 7.b load, last week the same load was showing the problem... but i
don't know why/how, this week it started working. I didn't changed any
pref/setting on my mozilla, but somehow the pages are loading fine.

Thanks for your efforts.
This happens constantly in IE at my library.  I don't think it's Mozilla.

(WFM, but my build is ancient - 1.6)

I am getting this problem with Mozilla 1.7b on Yahoo pages. If I go to the
following URL: then only the header of the
page will display. I can go to any stock symbol the same fashion and get the
same results. i.e. or all result in the same behavior.

I saw this with the default version of mozilla that came with my RH 9 install. I
have since removed that version of mozilla (1.2.1) and installed 1.7b, only to
get the same results.

I have cleared both my memory and disk caches, reinstalled 1.7b, etc... but
still can not see this page.

Related to bug 222069?

I don't see how we can block on this if we can't get reliable steps to reproduce
it. Also, if people are seeing this on Mozilla 1.2.1 (comment 10) then it's not
a recent regression and if it was a widespread problem, we'd have heard a lot
about it in 1.2 and 1.4-based releases (like Netscape 7).

Perhaps of note, since about a week ago, Yahoo! has worked at my library.  Maybe
it was a temporary issue with Yahoo!?

This just started for me. comes up with an (Untitled) title
bar and a blank page. This started this afternoon, with a previous 1.8a. I'm now

Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8a) Gecko/20040511

and still comes up blank. Further, the processing time for
this page is minimal. Not more than a second or so.

Due to this happening with no change to the browser, I'm wondering if Yahoo!
changed something.

Also, I will experiment with deleting cookies, etc., and see if I can get
behavior changes.

1) Search Cookie Manager for all cookies containing "yahoo."

2) Remove those cookies.

3) Open

4) Get the generic My Yahoo! page, with the option to log in on the left side.

5) Log in with name and password.

6) Select "Remember my ID & Password"

7) Click "Sign In."

8) Get a blank page with this URL (in my case):*http%3a//


An attachment with the cookie information added by Yahoo through this login will
follow shortly.

I just tested with a brand new profile, for no change.

1) Get the un-personalized ""

2) Log in as before.

3) Get "you are about to view an encrypted page" pop-up, immediately followed by
"you are about to leave an encrypted page" pop-up.

4) Get a blank page under this URL:*http%3a//

5) Get these cookies put in cookies.txt:	TRUE	/	FALSE	1086158153	I

So, this isn't a profile thing.

And today, the page comes up without a problem. Some weird programming change at
Yahoo? Some weird interaction with cookie's date code? Beats me...

FYI, using lynx from a UNIX shell (non-interactive) to illustrate yahoo's
reaction to certain user agents. Zero characters returned if useragent is
Mozilla/5. Suggests to me a problem internal to yahoo.

% lynx -dump -source -useragent 'Mozilla/5' | wc -c
Warning: User-Agent string does not contain "Lynx" or "L_y_n_x"!

I had the same problem, was able to resolve by setting
general.useragent.overrride to MSIE

Comment 21

I'm told it's a proxy issue in some proxy server versions. Apparently yahoo only
enables gzip encoding for a known set of userAgents. Thus even if your browser
transmits accept-encoding:gzip (as some lynx versions and usages do), but with a
non-Mozilla/5 userAgent, yahoo still avoids gzip, avoiding the issue.

True fix: upgrade/replace/avoid the problem proxy server. Work-arounds: forge a
non-Mozilla/5 userAgent similar to above; or leave userAgent as Mozilla/5 but
config to disable transmit of accept-encoding:gzip in prefs.js by:

user_pref("network.http.accept-encoding", "");
Product: Browser → Seamonkey

Resolving as WFM.  Comments indicate that this was either a server-side or proxy
problem.  If anyone disagrees, feel free to reopen and provide more info.
