The fit-to-window feature is mostly what I wanted, and it works properly. I wanted it to hide the recommendations column completely as I find those distracting, while having the video as large as possible without fullscreening the browser.

Better settings than youtube themselves. Obviously.

Worked well until it started crashing both my Zen browser and my wife's Waterfox with memory exhaustion.

It has stopped autoplaying next short, very irritating

Does not shuffle playlists on Firefox mobile. This is the only extension I could find that claimed to do this, but I was very dissapointed when the option was enabled and the playlist continued in order.

Im not sure how it is on desktop but it is really buggy on mobile firefox. Whenever you try to look into someone's channel and move to other taps such as the channel's home/videos, it just freezes. It doesn't let your reload nor get out of the page via return button. Also even when it works when you try to click the channel's other shorts it freezes. I tried turning on & off my phone but it still does it. Had to disable the addon.

Everything is fine, but the video speed does not work in built-in frames, for example, on Nexus

This extension imho is required for YT. No more shorts, no more videos you've already watched, block AI slop channels easily. Props to the devs... (slow clap).
