I'm seeing this problem a lot less now. KDE is now at version 4.10.1, Firefox 19.0.2 and Thunderbird 17.0.4 but both Firefox and Thunderbird seem to freeze at the same time. No other applications seem to be affected here.
** Also affects: firefox (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/963736 Title: thunderbird freezes at random : must be killed and reload To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/963736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
