I encountered the same issue today without warning, except for me, opening a new window from File->New Window did not resolve the issue. Starting Firefox from the command prompt gave no errors or warnings. The only resolution I could find was to first start in safe mode (which had window decoration), then start in normal mode (with all add-ons still enabled). Everything is fine now.
Any idea how to better look for errors/warnings/messages in the future? -- 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
