It's good for videos - but why doesn't it work for audio too?? Doesn't work for Bandcamp, Soundcloud or similar. It does everything that I want otherwise, which is mainly changing the volume while dragging the slider (something other boosters don't always do).

effective and swift to use very nice

literally does not work

So good i made a Firefix-Account just to write this feedback (yes srsly) it does improve things a lot for ppl who dont have a good speaker! Only mild annoyance: when i open a vid in a new Tab the settings arent applyed there, meaning i have to manually adjust the amplification again! While not a biggie, once thats fixxed i´ll give 5 stars!

After a month, paid service term will start.

It's very good for me... Thanks for the deveoper...

Completely mutes the audio regardless of settings. Latest Ubuntu snap firefox.
