Randomly breaks. It's fixed in 3.0 but for some reason it's not on firefox.
The extension is good, but sadly not on the 3.0 version, which adds some QOL settings.

Sometimes it works and sometimes it doesn't. Not sure why. Does anyone know of a good alternative?

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

doesn't work well anymore and no more update from the dev..

Amazingly amazing

App does what you said

Works very well on Firefox ! On chrome, it has some issues with the 'Expand' button

impressive list of customizations here
