I couldn't adjust the volume at all except for YouTube. What you really want to tune is the web application.

Doesn't work consistently + breaks TikTok

it used to work when i first got it, long time back and i REALLY loved it... but haven't needed to use it for a while and now have noticed that for some reason, now it really only works for me like 2% of the time, it however does constantly completely mute any tab that i try to use it on and the only thing that can be does is to reload the tab, which of course makes the sound volume reset back to normal. if you ONLY want to watch youtube in one tab, this add-on would be fine, that's about the only site i can get it to work with any more... i would also suggest, next time you update this extension, add some settings to it where i can change the automatic default and that it would apply to ALL tabs, or at least have that option... i wouldn't have any issues with the extension at all if i could just go into settings, set it to default 400%, across all tabs, wouldnt be any need for tabs reloading or adjusting it for each individual tab or video, wouldnt have to wait for the video to already start playinig before ii can adjust the volume, two little suggestions would fiix the whole extension, for me anyways. i'm so disappointed but until it get's fixed, i'm going to try some of the others that reviewers have suggested for now since this one doesnt work :(

Not working

BEWARE of ADWARE/SPYWARE/MALWARE !!!
600% Sound Volume extension breaks MFA functionality on kongregate.com (after signing in with username and password another window should open to enter security code received by email, but it doesn't when this extension is enabled).
An add-on that supposedly boosts audio volume shouldn't break website sign in process. Unless it's trying to do something shady in the background, like stealing user credentials or something.
If you care about your privacy, I recommend to disable and remove this extension ASAP.

не работает Версия 129.0 (64-битная)

used to work but doesn't anymore

doesnt work got earraped countless times

Review changed, due to adding adverts to the extension. I understand you want to make some petty cash off your work, but I don't want adverts.

Doesn't work with soundcloud

Breaks Twitch clipping feature, cannot clip, issue reported over 3 years ago still not fixed. The 'error #4000' thing. Reported on r/firefox and only solution is to disable this addon.

Its crap, it goes up down on tabs its crap, it blasts when you dont need it its not doing shit but increasing volume no respect no love, its crap.

causes error with video playback on certain sites, has gone unfixed for seemingly 2 years according to reddit

privacy violation, blocks videos from playing like twitch clips and gofile. the tracking removed version works properly.
