YouTube playback speed settings don't work on Firefox

[Melonadev]

As long as I have this extension enabled on a YouTube video open in Firefox 90.0.2 (64-bit), the speed settings don't work.

In fact, it seems like another user on Reddit posted about a similar issue 13 days ago. And interestingly, the commenter noted that several extensions that adjust the volume of audio playing in Firefox caused this issue.

Add this extension to the list.
