A wonderful add-on with several features (like a compressor) that set it apart from similar extensions. My only suggestion would be to make the font size larger on the volume level icon. It's barely visible now; you have to look closely to see it.

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..

Works fine but I'd welcome if there was an option to limit the volume range to 0-100%. I don't need the extra boost and the range of the slider for 0-100 is quite small.

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