However, when changing the maximization state, some visual gitches occur. I didn't notice this glitching when running Kubuntu or Ubuntu Budgie on two separate systems. To try this, go to your Firefox Menu, click Customize, and uncheck "Title Bar" at the bottom left. Then unmaximize the window and then remaximize it. What it's supposed to look like: https://pasteboard.co/HM0h8oB.png Unmaximized (note the large transparent section): https://pasteboard.co/HM0hpud.png Remaximized (note the duplicate set of close buttons): https://pasteboard.co/HM0hCf5.png Also another interesting bug I noticed...if you try to use Firefox in the no titlebar state with the global menu enabled (e.g. Contemporary, Cupertino, or Mutiny panel layouts), the window buttons are not placed correctly, being on the window border.
