Does minimizing and un-minimizing work to recover from this?

• 1830721 - firefox nightly fullscreen has borders around all sides when using userChrome.css -moz-appearance,release version has not.
• 1830681 - Fullscreen mode has padding, doesn't occupy the whole screen

No, it doesn't help.

Which DE version do you use (113.0b9 is current) ?

Yes, it's 113.0b9.

I can replicate the issue in Win 7, even in Safe Mode with hardware acceleration off. Doesn't happen in 112.0.2 nor Nightly.

Ok, looks like this issue has been solved with the recent 114.0b1 update.

Mark it as resolved.

I have exacly the same problem. It started today after update to newest 113.0 :( How to get rid of those borders ? I can't see newer (114) update available for me. (im on W7)

I reverted back to 112.02 and the problem is "solved" ...

Nobody knows how to fix this or will it be fixed in new update (when) ? as it would be better to use safe (updated) browser..

We expect to include the fix in the 113.0.1 dot release tentatively scheduled for 23-May.

In case you missed that, let me say again that I'm using the Developer Edition of Firefox, not the standard one. The latest version of the standard Firefox is 113.0, so for the time being you can switch to the Developer Edition until the next version is out.

Try to update to 113.0.1, should be already released => https://www.mozilla.org/en-US/firefox/113.0.1/releasenotes/

Just got the last update . Fixed. Thank you

it works, thanks.
