i have not used it and it force me to rate it

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).

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...
