I like this addon and I've been using it for years now, sadly it doesn't work most of the time since last year or so

Used to function beautifully allowing for a bunch of customizability and functionality. Now, it no longer works. From a bunch of other reviews, it seems like this extension is no longer being updated by the dev? What a shame.

ดีมาก แต่พออัปเดทแล้วการตั้งค่าที่เคยตั้งไว้ หายกลับไปเป็นค่าเดิมหมด

Doesnt work, people say it wont be fixed. Very sad.
Anybody can recommend replacement that allows convenient playback speed control with ctrl+mouse wheel in x0.1 increments with speed limit at x4 or higher?
Another important thing is control of saturation and contrast. Please help!

The version 3 on chromium based is pretty good, but this is all buggy and bad. Not using again until the firefox version is updated.

I've been using this for years and I finally took the time to look through what this add-on ACTUALLY offers and WOW! Always use this add-on if you love yourself.
