   Works OK ish but then randomly applies a setting from a specific channel globally - i.e. bugged mess, not updated in years - bit of a shame on the author.

   Fair enough. I created this during my spare time, and it works well enough for my personal use. I released it for free in case others found it useful. If it doesn't do what you need, there are many others available.

   Is that possible to make it work on YouTube music too? Right now after each new song it changes it's playback speed back to 1 and requires manual setting for each song even when default is different from 1 it starts every song from 1 speed. Could it be maded like with videos? At which it would hold setted default speed without going back to 1.

   Works really well, awesome! The only gripe I have with this cool add-on is that it does not take into account that the browser (Firefox in this instance) always assumes the tab is set to zero playback speed. The result is that if I want to reduce playback speed by one tick, I end up at .75 and not the expected 1.75. Any chance for a fix? Can you take the actual current speed into account? Keep it up! EDIT: Seems to have stopped working for a couple of days now. :/

   Very nice lightweight extension that works very well almost every time. I'm not sure why but some channels appear to be immune to having a default speed set. I've only found 4 so far. Would love to know if there is a way to fix this.

   It works sometimes, but too often I'll load a video from a channel I watch frequently, and it forgets my speed setting. And if you skip far ahead in a video, so YouTube has to reload the stream or change the quality level, the speed adjustment is consistently lost.

   works fine and all but i'm struggling to figure out how the per-channel setting works, because it never seems to save the speeds i set
