Firefox keeps crashing when browsing websites

[Ketil]

After I got the new Ubuntu update to version 9.0.1, I've had many crashes, meaning that Firefox just vanishes and I get the "report error" dialog. Today this has happened two or three times while browsing the Norwegian finn.no site, a website to buy and sell stuff. The first crash was when I opened the bookmark, I had another crash when I tried to submit a search. I think the crashes always occur when loading a page, and other websites may provoke this as well.

Ketil, thank you for reporting this and helping make Ubuntu better. However, your crash report is missing. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer. First, execute at a terminal:
cd /var/crash && sudo rm * ; sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get -y install firefox-dbg && sudo service apport start force_start=1

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

Now reproduce the crash, then open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'. If you run the command against the crash report and a window pops up asking you to report this, but then never opens a new report, you would be affected by https://bugs.launchpad.net/ubuntu/+source/apport/+bug/994921 . In order to WORKAROUND this, one would need to open the following file via a command line:
gksudo gedit /etc/apport/crashdb.conf

and comment out the line:
'problem_types': ['Bug', 'Package'],

by changing it to:
# 'problem_types': ['Bug', 'Package'],

Save, close, and try to file the crash report again via:
ubuntu-bug /var/crash/_my_crash_report.crash

Please follow https://wiki.ubuntu.com/MozillaTeam/Bugs when you file this crash report so the necessary information is provided.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently.

Thank you for your understanding.

Thanks, but this bug report is two years old... I have long since forgotten about this, and I've upgraded Ubuntu (and changed hardware?) a few times. I'm using Firefox 26.0 now, so I can't reproduce this.
