48765 - Improperly installed acrobat plugin freezes Mozilla Window content

Status: VERIFIED INVALID

(Core Graveyard :: Plug-ins, defect, P3)

Description

[WD]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; m18) Gecko/20000811
BuildID:    2000081108

My system does not have the Adobe Acrobat plugin properly installed on it.   I
recently deleted my Windows directory, and re-installed Win98SE cleanly.  I then
Installed Netscape, and also Mozilla.   I have *not* installed the Adobe Acrobat
software or plug-in.   (Though the files are still on my HD somewhere)   When I
try to open a PDF file in Mozilla, I get an error message from the Acrobat
Plug-in saying that it cannot launch Acrobat.   I click OK, but the error dialog
is still there, and I can't use that Mozilla window anymore.

Reproducible: Always
Steps to Reproduce:
1.Go to http://graphics.theonion.com/pics_3627/infograph_3627.pdf
2.Click OK
3.

Actual Results:  The Dialog remained after clicking OK, also preventing that
Mozilla window from doing anything else.

Expected Results:  Clicking OK dismisses the error, allowing me to resume using
Mozilla.

With Netscape, the first error message is the exact same as Mozilla.   After I
click OK, it then pops up a second, different error message from Netscape saying
that the Plug-in could not be loaded.   When I click OK on that second error
message, I can continue to use Netscape.   Mozilla does not have that second
error message at all.

Marking Future. An edge case and I think it will be difficult/impossible to 
reproduce this situation.

Please update your build. This WFM Gecko/20010308

this is easy to reproduce. copy the acrobat plugin to your plugins directory, 
use regmon to find out what registry entries it looks at. delete or (nt) make 
those entries unreadable. restart mozilla.

I've had this problem in nc4, it's really annoying, but imo it's adobe's fault. 
[it crashes netscape4]

This is really easy to do :-)
NT: run regedt32 [as admin], browse to: 
HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe
get permissions for that key.
pick a victim account, and add it to the permissions list, set it to deny 
access. <ok>

run mozilla.  The result is a horribly confused (but not crashed) mozilla 
content window as soon as you try to open a pdf (i chose one of acrobat's help 
files).

ways to escape:
* go back
* use a bookmark
* create a new window
* select a url from the url drop down

things that are broken until you escape:
* urlbar edit field
* search>search the web
* view>translate
* Debug>*, QA>*
* Help>Release Notes, Help>About Plug-ins
* File>{Save As, ..., Print}

View>(Z) has appeared and other strange features wrt that menu :-)

I can demo this for anyone if they're interested.

This was reproduced using a cvs build from this weekend.

Marking this bug as INVALID. There are many ways you can cause mozilla 
to crash or freeze by mucking with the wrong files or registry entries.  
Deleting your Windows directory or changing registry keys is just asking 
for trouble. Use, UNINSTALL instead or simply re-install acrobat again. 
Be sure the nppdf32.dll is not in your 4.x plugins folder.
