When I click the fullscreen button on a video, such as YouTube or Netflix, I find that upon exiting the fullscreen video and going back to normal screen, Firefox's window size is now maximized, when it was a smaller window before clicking the fullscreen button.

I am running Ubuntu 21.10 and I don't recall having the issue in previous versions.

Hello,

I could reproduce this bug on 21.10 with Firefox beta 95.0b7.

This seems to be a known and unfixed bug. If you would like, you can post on its bug page so that someone is notified that people still have this issue.

Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).


You can try Firefox from the official Mozilla server if you currently use a version from the repositories of your Linux distribution to see if it behaves differently.

I can confirm that an official build, from the Mozilla repos did not help, but renaming xulstore.json and restarting did.

Thank you cor-el (even though I never really noticed or cared about this bug lol)

Hi, Thank you for this quick response and helpful links. Renaming/removing xulstore.json didn't solve the issue for me and downloading from the official Mozilla server didn't change anything either. I'm going to keep researching and if I find anything that works for me, I'll share it here.

I'm not able to reproduce in any version of Firefox. How about creating a short video showing the issue.
