White line at the top of fullscreen window

I'm not sure when it started happening, but whenever I'm watching something full screen, or just full screening, Firefox on Mac, there's this thin white line at the top of the window that's very distracting. Has this been happening to anyone else and does anyone else know how to get rid of it?

Can you try restarting into Troubleshoot Mode (from Help menu) how it works without customizations enabled, and also trying out a few other themes to see if there's any difference?

Troubleshoot mode seemed to do nothing, but changing to a light theme temporarily fixed it. But any dark theme selected and the bar returns, seems to be a bug with every dark theme

Can you share your macOS version please? (It doesn't exhibit for me on 15.7.9 Sequoia trying a couple of dark themes.)

Currently on MacOS 27 Golden Gate. I think it was here in Tahoe too
