Does not work on all sites. I wanted to use it for Rumble but totally useless.

As soon as this extension was installed all my tabs went mute even while playing. Even when the extention showed the tab was not muted.
A fine idea, but not fully there yet

For some reason, it muted sound on all other websites when enabled.

The idea is good, but the extension is not working as it should.

I changed the volume of "web.whatsapp" and when I was in youtube it was turning the volume down until I change it manually in the video, but then it turns down again in a few seconds.
