Good..one issue...there is a quite large gap/space between bottom of video and to where comments start.....I would post pic but imgur links not allowed here(lame)...not sure if its just for me having the large empty space?...I have clean install firefox on win 11...anyhow..TX..P.S..when exiting full screen the entire browser window becomes smaller...I think someone else mentioned this aswell.

Thanks a lot, the comment scroll is back. It works instantly, but has major issues.
Now I saw the complete firefox or librefox windows goes out of fullscreen on macos, when you use the multiple desktop function (spaces) in fullscreen, hope you know what I mean. And it's at least here on macos and firefox not a actual fullscreen.

Thank You! Now i have my volume with mouse scroll back for my TV!

It works well, but when I press esc firefox gets retored down, and then I have to maximize it. It's annoying, but I miss scrolling down while in full screen

Very glitchy and doesn't work sometimes.
