I love this extension, and it's my hope you'll reconsider releasing v3 for Firefox. Even if it's a sideloaded release if that's possible (not on AMO).

For people looking for alternatives, "'Improve YouTube'" could be good. Not sure of the features comparing to this but it does offer themes and other customization options!

I don't use all of the options. love it.

great

Great add-on but do wish there was a option to not play the video and only play the audio :)

Amazingly amazing

App does what you said
