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!

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.

Functional. BUT please whitelist music.youtube.com domains or others which may not work well having a non 1x speed default.

Works as expected: fix video speed but you need to be on the Youtube tab.
I like the idea to have icon in the awesome bar, however I was expecting :
* to see it on every tabs, not just youtube, so I can change speed from anywhere
* that the value reflect current setting instead of a fix `3x`
* valid input using keyboard `Enter`

Improvement will be to have:
* keyboard accessible extension
* a quick way to set back to 1x speed

Simple, and can set with 1/10 step. That's what I need!
Thanks for plugin.
