Cool plugin..

It can boost volume without distortion for the audios recorded in low volume.

But if the audio is louder, pulgin compresses the audio. There seems an internal knee, set to an absolute db for 100%. Actually it works like a compressor with high ratio.

Which I am ok with that.
But it would be better if there is a bypass switch.

works on everything except web-spotify, will be adjusted if there is fixes

Works well enough, I just wish I could set a default volume level so I didn't have to keep boosting the volume every time I open a new tab.

A life-save for Firefox's low volume issue that I cannot solve for years. I would like if the setting would re-apply on a cycle to cover in-frame videos, like learning video playlists.

Great add-on.
I just hope to make it fixed for all websites, or at least, for browsing session.

The app really does boost the volume, which I needed, so I'm happy about that. I just wish it would keep the volume the same from site to site. Every time I go to a new channel or website, I have to re-set the volume level. Any way to keep the setting??
Edit 7/28/2022 - What is going on with this app? I have to re-set it at least 50 times a day now. It goes off by itself; it goes off when I change tabs; it does off when I change streaming channels. And I've had a lot of crashes lately - can't totally tie it to this app, but it's suspicious. I keep using because I need the volume boost, but it's getting very annoying.

Couldn't find anywhere to suggest, but can you adjust/add the ability to alter "step" other than 10? I like having more control to be able to go by steps of 1 (or even .1) if possible. Thank you!

Work very well. some times is anoying that when a new video/episode i got to move the slider to get it to work again.

Great Extension. If you could add global boost feature, to enable me to boost volume for all open tabs.

Works well, but for some reason when installed (even disabled) it causes the chat window on twitch.tv to disappear every time you resize/clip the window in Windows 10. Inconvenient enough for me to uninstall.
