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 and the developer has abandoned this addon for Firefox.

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 From a bunch of other reviews, it seems like this extension is no longer being updated by the dev?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.

Extension is abandoned by the developer.

It's great at increasing the video size... When it works. When it doesn't, there's no button to press that will make it realize it didn't work.

All was fine until I heard that support for Firefox was halted indefinitely. Very disappointed, honestly. Might as well take it down at this point.
