Works flawlessly for the most part, only issue I've seen is that it detects transition screens in videos as sponsorship ad breaks and tries to skip them, which can make the video feel unnecessarily choppy. Specifically this was occurring on videos from the Formula 1 youtube channel.

Otherwise, a must get extension.

Using video filters and changing options like brightness lowers videos frames, making videos choppy, unwatchable. Fix please!

Bem legal :-)

Good, but for some reason the extension kinda breaks and I have to run it again, doesn't always happen though
Just came back here to downgrade my rating. It has been breaking pretty often now. I'll reinstall it, but I wish it wouldn't break all time time. Amazing features though.

As close to perfect as I can ask for.

Perfect

A very useful tool for people who want to customise their YouTube experience.
It has been available for most browsers since about 2014, (I could be wrong about this, but it has been there for at least eight years.)
The developer is one of the few who actually listens to users' requests. Thus he almost always develops and implements functionality requested by real users.
One last thing;
In spite of the unpredictability of YouTube's proprietors (Google), who have changed everything multiple times, this developer has always been ahead of the game, and still is to this very day.

Nagyon jó.
