Diễn đàn hỗ trợ Firefox

Maybe after update, or i dont know why, but now. when youtube (or any other videoplayer) in fullscreen - taskbar menu is visible (Is on topscreen). In google chrome problem is not repeats. I'm using StartAllBack app for classic start menu, but till that day all was fine. I checked on two devices with firefox - the same problem (StartAllBack or windows version wasnt cahnged). Windows 11 24H2

This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?
