Doesn't work for some websites, but I can understand its probably something to do with them and not the addon.

Good for raising volume or lowering volume for a specific tab. Great for making Youtube Music quieter.
Can adjust volume in 10% increments, from 0% to 600%. But does not save volume for if page is reloaded or closed. Adjusts volume for just one tab, not the whole website.

Прекрасно помогает справиться с тихими видео, жаль что не работает с Яндекс.Музыкой

Good , if full fledged stereo output is incorporated, will make this add on an top performer

Have to change the volume on each tab. So some streaming sites I have to change the volume every single episode. Not a huge gripe but it would be nice if it applied to each site

Does what you want it to. Small bug though. Twitch clips are broken when this extension is enabled. Could you please fix whatever the issue is, or add a feature to disable the extension for X domain.

I just wish it saved the setting for each page; besides that, it's perfect.

There should a global option other than that its good

I love this add-on. I was having trouble with some streaming sites just being too quiet even with everything on max volume, and that's no longer an issue. BUT, with this add-on enabled, I can no longer play videos on TikTok. It only shows a thumbnail, and clicking it does nothing. Once I disabled this add-on they worked again, so I know it's this one causing the problem.
