This behaviour (Unresponsive application) is called hang or freeze. A crash would mean, that the process suddenly dies and as a result the application windows just disappear.
Probably the hang issue might be caused by some plugins (e.g. Adobe Flash). You can disable plugins in the addin menu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434848 Title: firefox crashes at some websites To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1434848/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
