Thank you for reporting this to Ubuntu. Sometimes Firefox profiles can become corrupt and/or extensions can conflict. Could you please try this with a new profile and see if the problem still exists? You do not need to delete your old profile to test. If this helps, you might want to try to disable all your extensions and re-enable them one by one until you find the problematic one.
You can start the profile manager with the following command: firefox -ProfileManager ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/936633 Title: Firefox 10.0.2 not respecting system proxy settings in 64-bit 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/936633/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
