Works okay but I often need to disable it and enable it again for the control to show. Also, when I write Youtube comments I tend to use the back arrow to correct mistakes and this causes the video speed to slow down. I don't think simply pressing back arrow should control that?

Unfortunately, it would seem that this add-on now only works about 50% of the time. I've been experiencing more and more videos lately where the bar is completely missing and the quick keys don't even work. I suspect YT is doing something on their end to block such add-ons with experimental A/B testing and such which is why it only works some of the time (in true greedy fashion they want to charge/only let premium members adjust the speed higher than 2x).

Age of the video, resolution, etc doesn't seem to matter, sometimes it just won't load with the video even after refreshing the page.

50% of time works every time!

Most of the time this works pretty well, but like 20% of the time there's no speed up in the corner. The icon appears in the URL box, but it's doing nothing to the youtube video.

works, but needs to go away in full screen

module marche ,mais je cherche plus d'incrémentation ,
dans le sens certaine video son ok a 1.25
mais impossible de comprendre a 1.5
d'autre parle lentement 1.5 c'est ok ,
et cherche donc un module avec plus d'incrementation 1.125 1.25 1.375 ...
pour que cela soit audible et compréhensible ...

cannot display the current speed accurately, stuck at '1.0' despite speed control functionality is working
