Works perfectly for Youtube and Facebook videos. Just shy of five stars because this app's "homepage" redirects to a regular spam-riddled blog, making the app kinda untrustworthy.

This add-on is a serious lifesaver. The only thing I'm not 100% satisfied with is that the tab volume doesn't save when you load a new page (for example, starting the next episode of a show). That might be an unavoidable limitation on Firefox, though, and it's not a big deal to readjust the volume at all. I'm super grateful for this add-on :)

A good simple volume slider for Firefox, would be better with a dark theme

works great most of the time. but like others say, it makes some website videos not work, or if you try turning volume up some sites will break the audio.

It would have been given a 5 star, if I could set it and leave it at a setting. Better than not hearing! Much better!

bandcamp refuses to load tracks after volume adjustment, have to reload

Works as expected.

very good
