Per-Tab Volume Control is the best volume extension I’ve ever used. It would be even better if it added keyboard shortcuts.

This screams "AI" lol I don't care tho, I like the idea and how it looks. it's just, it didn't work for me..
I need this for a specific website that has alerts but doesn't let you change the freaking annoying sounds or control their loudness. but they are VERY essential..
so this extension fits here like a glove.
needs more testings tho..

This extension does a great job. A particular highlight for me is that you can turn down the volume on videos. I often find that videos are much too loud when you start them. It's always very unpleasant for me when videos start too loudly, but that's finally come to an end.

Does what it says on the tin. A separate make-up gain control would be usable, but the threshold seems to compensate accordingly.
