Public bug reported: After a recent Firefox update (I think this started after the Firefox 95 upgrade), opening Firefox often opens a window with a visible title bar that indicates that the application in focus is Firefox but the content area is invisible because it has the frozen image/background of either the windows/application behind the Firefox window or the desktop background image if there are no windows behind Firefox.
The Firefox shortcut keys work and I am able to open a site by pressing Ctrl+L to focus the address bar and type a domain name/URL. The website/URL loads okay but nothing is visible because of the content area being hidden by the frozen image. Resizing/minimizing+maximizing the Firefox window doesn't resolve this issue. However, when I launch Firefox from the terminal, it works properly every single time. So it looks like there might be some issue only when launching from the Firefox application launcher (.desktop file).
