Same for me, everything ran great until I upgrade to Raring from 12.x Firefox 20.0, Thunderbird 17.0.5
The only thing I recall about upgrading is that new nVidia drivers were install during the upgrade. I was not using Oxygen GTK theme, I was using the Air Black Remix for Window Decorations and Glassified for desktop theme. Switched both anyway to see if that helps. -- 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
