Thanks, so this is basically the same underlying problem as bug 801699. The issue is that it takes ages to find the node for each event coming from the HUD, although this doesn't explain why it's happening on focus changing.
Perhaps Ryan can help figure out whether those events are actually coming from the HUD :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/964584 Title: Firefox hangs temporarily everytimes it receives the focus To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/964584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
