firefox freezes when greater than three windows are openened

[Cameron Braid]

Binary package hint: mozilla-firefox

if I click the firefox icon twice, two windows open and are useable. If I click a third time, the two windows freeze, then turn black (by compiz), and I have to 'killall firefox-bin' to kill them.

note : this is in latest gutsy

[Cameron Braid (cameron-braid)]

note : the same thing happens with desktop effects disabled.

I can confirm this, according to gnomefreak on on irc its either java6 or pango related.
Disabeling both javascript and java in the settings didn't work though, deleting my settings folder (~/mozilla/firefox) however did.

firefox version: 2.0.0.6+2-0ubuntu4

[John Vivirito (gnomefreak)]

Ok ive thought about it and it might not be pango, can you please run the following command and try to reproduce the issue than close firefox.
strace -f firefox &> /tmp/strace.log
than attach /tmp/strace.log to the bug report. you may have to break the file down to smaller peices depending on your net connection.

[John Vivirito (gnomefreak)]

Cameron can you please try running MOZ_DISABLE_PANGO=1 firefox and see if you are able to reproduce it. if not please follow the instructions at: https://wiki.ubuntu.com/MozillaTeam/Bugs
on trying with a new profile. I had Bart use new profile and problem no longer was reproducible at this time.

[John Vivirito (gnomefreak)]

Cameron: also was this a clean install of gutsy or a upgrade from another version of ubuntu if upgrade from what version?

[Cameron Braid (cameron-braid)]

this was a clean install of gutsy from tribe 4, then fairly regular dist-upgrades to keep current.

I'll run through those tests in a few hours when I am able to reboot into my gutsy install.

Cheers,

Cameron

I ran your strace command, then chose File -> New WIndow twice, waited for the window to turn black, then clicked the cross to close, then clicked Kill

[Cameron Braid (cameron-braid)]

MOZ_DISABLE_PANGO=1 firefox doesn't make any difference

[Cameron Braid (cameron-braid)]

firefox -P, then creating a new profile solved the issue.

I also tried deleting ~/.mozilla and running firefox as normal, which also worked a treat.

Thanks for your help.

[Bart Cerneels (stecchino)]

After accedentaly deleting my profile folder I wasn't able to reproduce. Now that I installed the addons again the bug reappeared.

The addons are:
Download statusbar
Google bookmarks button
Google toolbar
Link Alert
PDF Download
Signature
Stop-or-Reload Button
Tab Mix Plus

[Bart Cerneels (stecchino)]

MOZ_DISABLE_PANGO=1 didn't help either.

[John Vivirito (gnomefreak)]

Bart Can you please remove all the above add ons and install them one by one to find out what one is breaking this.
Cameron, Can you please give a list of your addons/extentions/themes as well.

[Cameron Braid (cameron-braid)]

The only two add ons that I had installed were

* Firebug : http://www.getfirebug.com/
* Web Developer : https://addons.mozilla.org/en-US/firefox/addon/60

I deleted my profile, and added both of these add ons, but I could not reproduce this bug.

[Bart Cerneels (stecchino)]

OK, I finaly had the chance to test wich addon causes the freeze.

After adding all addons one by one and restarting, then testing by opening a third window.

The culprit is Google Toolbar version 3.0.20070525L. I've deleted my profile and installed only Google Toolbar just to be sure.

I will test more plugins now, maybe it can be traced to a certain XUL funtion or similar.

Here is a screenshot of my addons window of firefox.
I disabled google toolbar and now no more freeze on #windows > 2.

[John Vivirito (gnomefreak)]

Google tool bar and other google addons are causing all kinds of bugs, one of these days when im feeling a bit better i will get up with Alexander to see if this is something we can work around, but in all likelyhood the idea will be rejected as there are reasons we dont/cant support all adddons but i will see what we can do if anything

[Alexander Sack (asac)]

Bart, did earlier google toolbar versions work for you?

[Bart Cerneels (stecchino)]

I never experienced anything like this bug. Unfortunately I could not find older versions of the google toolbar to test this with.

[Cameron Braid (cameron-braid)]

I can confirm that the google toolbar (version 3.0.20070525L) causes this issue in gutsy.

is there a workaround ?

Hi, I just wanted to comment that a) this was useful, b) I was experiencing the same problem, c) disabling the google toolbar fixed the problem.
