This problem is not with Firefox only. It can be with any window. This is a possible duplicate with this one: https://bugs.launchpad.net/ubuntu/+bug/1171451
The freeze happens to the last window that is to be minimized. For example if you have 2 open apps. If you minimize the first one, no freeze will occur. But when you minimize the second one the freeze will occur. When I switch to another workspace and then come back, the freeze is gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1163503 Title: Minimizing firefox makes unity freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1163503/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
