So far, it's working well. I tested it and it doesn't require login or unnecessary actions. It functions on other websites besides YouTube, including screen flipping, which is promising. I can speed up the audio, and it avoids the extra YouTube cost for 4x speed. It seems to be working perfectly, including on the other two sites I've tried, unlike another extension I tried that slowed down the video. The brightness control also works, which was my main reason for getting it. While it isn't as advanced as some other programs, it works, and my old one no longer functions because it's on Manifest V2. I give it a thumbs up and all the stars. Hopefully, it doesn't make me see them if I'm wrong.
