Tried with Firefox for Android Nightly (120.0a1), but it doesn't seem to do anything.

I added this extension specifically for it's function to reverse youtube playlists, but I don't see the button to do it.

everything good, but currently if a set speed x2, it just work for the first video, later, another videos is at x1 speed

It normally works really well.
But within the last couple days it's not auto-playing the start of playlists despite the fact that i never turned that function off in the extension.

You should find a name for that extension, cuz it's the best.

I'm giving 5 stars because of how well this addon works on Chrome, but I was wondering if you could fix the broken parts for Firefox as well.

Right now, the "player size" options are broken.

You guys have always been great about adjustment in the wake of youtube's erratic updates/changes, so thanks in advance!

Youtube is breaking things as they always do. I am currently having trouble with speedup not working, but I am also wondering if anything can be done to block the new pause recommended videos at the bottom. Thanks as always guys.

Fit to window and custom playback speed are still currently broken on firefox

Disabling shadow around a video on hover, disabling the 5 second skip animation and other player appearance options are now also broken

I have disabled the extension on firefox. Aside from things being broken, it is now also causing youtube to slowdown to an unwatchable level. I will be using alternatives until the extension is fixed

I have a problem in Full Player, when i'm in full screen i see a white gap below, and this is cause by Player Size Full Height (Appearance>Player>Player Size> Full Height) but this is annoying because i use that option when i'm not in full screen to make the video player more bigger, but when i use full screen i see a white gap space like a footer.
