[BugBot [:suhaib / :marco]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Cannot reproduce, works without a problem (Firefox 103, Fedora Linux). Please disable all and any extensions and try with a new and fresh Firefox user profile.

Still the same, even a fresh firefox install does change anything.
I'm on gentoo, using the firefox-bin pkg, I also tried 2 flatpaks: firefox and librewolf and it's the same.

maybe it is due to a misconfiguration on my part, I use Sway.

I have the exact same problem on KWin Wayland, so the issue doesn't seem to be limited to Sway. It happens only on one of my monitors, and only when the window is maximized. Putting it in windowed mode and then remaximizing temporarily fixes the issue - the hamburger menu then works for a minute or so until it breaks again. Said monitor has a higher refresh rate than the others and is on 1.25x scaling, which may have something to do with it?

It also doesn't just affect the hamburger menu; the "puzzle piece" add-on menu is affected as well.

Hooray, it appears to have been fixed! At least I can't reproduce the issue on a fresh profile in Firefox nightly 147.0a1 (2025-11-19); unlike Firefox 145.0 where it happens consistently, even on a fresh profile.
