I can confirm it I am having the same kind of issue with ubuntu hardy heron 8.04 running compiz and with an Intel 945GM video card.
Desactivate/Activating Addons would reset firefox and fix the problem temporarly A reboot can fix the issue temporarly. Stopping Compiz Fusion DOESNT fix the problem. The Window decoration going away seems kinda random. I tried desactivating most addons (I kept the ubuntu addon that was there by default) but the problem appearing again after a while. Right now trying to run firefox without any addon. Resizing and moving the firefox window do not work anymore when the window decoration is gone. The firefox takes all the screen space when that happens actually and firefox 'flashes' a bit when switching windows/workspace. -- Firefox opens without window decoration with Compiz https://bugs.launchpad.net/bugs/251617 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
