Weired tabbar UI bahavior on macOS
Firefox 102.0.1 macOS 12.4
When firefox is opened the UI is normal as shown in the first screenshot. But if I clicked any menu item, the tabbar displayed in a weired way as shown in the second screenshot.

What you're experiencing is not normal behaviour. Let's try refreshing Firefox. This will purge a lot of your Firefox files, while retaining most of your personal data. For instructions, check out the following article: Refresh Firefox - reset add-ons and settings

Hi, This may be a bug in the theme you are using. Can you try switching to the default theme and tell us if the problem still exists?
Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
The problem still exists after switch to default theme and disable hardware acceleration. Firefox hangs when starting in Troubleshoot Mode, I have to force quit it. I have not use an userChrome.css
