Which addon are you using for youtube?

[jholman]

I wrote a bookmarklet. Works on all non-iframe audio and video.

javascript:void%20function(){document.querySelector(%22video,audio%22).playbackRate=parseFloat(prompt(%22Set%20the%20playback rate%22))}();

Here's a non-interactive version

javascript:void%20function(){document.querySelector(%22audio,video%22).playbackRate=2.7}();

"<"/">" buttons decrease/increase playback speed (up to 2.0).

For Safari there’s Dynamo, too, that lets you skip ads apart from changing the speed:

But I suspect they're all mostly similar

Enhancer for Youtuber

This is a game changer.

I just modify it directly in the console (I have to search to look up the command every time).

Hit the Up arrow key in the console; in Firefox at least, command history persists across sessions.

For reference; $('video').playbackRate=3.33

The playback engine mutes audio below 0.25x and above 4x, not configurable.
