Probably the best option so far in software volume boosters, at least if you're mostly using Youtube. Though, this plugin (like all others of the same genre) fail to keep the volume setting for a site. So for instance if you watch a YT video and set it to +8dB, then watch a second YT video, you'll be back to +0dB and will have to manually set it back to +8dB or whatever. This is very annoying as unfortunately I have got one of those 800$ Acer P.O.S. laptops that have the speakers mounted ON THE BOTTOM so any sound is effectively half as loud as it normally would be on any normal laptop. I don't know what they smoked while designing this laptop, but thanks to your plugin, I can AT LEAST understand what the Youtuber says when volume is at 100% in Windows. If you could make it so that it retains the +dB setting for a given domain name or at the very least, have users edit the default +dB value to something else than +0dB it would be 5 stars out of 5!

Had to uninstall because it randomly requested all data permissions without any change notes on Github or "Release Notes" section in the extensions settings.


Edit Response:

I see. I'm fine with the increased permissions if it is allowed to do that now. Just wish there was notes somewhere explaining the change just to be sure your Mozilla account didn't get hacked or something and malicious code was added lol.

Is there any way to make it work on gogoanime.llc or sites that use a similar player?

Thanks!

Lightweight, simple, effective. Three words to define this wonderful add-on, it is also FOSS and respects your privacy which is extra points in my opinion.

Does increase the volume but i search for an addon that can decrease it and this feature does not work tried it on youtube music

Works great on youtube, but is there a way i could make it work on fmovies? maybe by changing the video player?

The only volume control add-on I have found so far that:
- does not remove volume
- actually boosts volume above the maximum
in addition to having a great minimal light/dark design! Thank you very much, I really needed this to make my tabs audible (:

Edit: Thank you for merging and improving the keyboard control improvement! Already in love with it.

Love it. This add-on doesn't affect videos full-screen mode. Extension on Chrome require you to press F11 to go full-screen. I hate it. This add-on does what it's supposed to do. Good job!

Works as intended, no bloat. Thanks !

This extension is fantastic! its so simple and lightweight, yet so effective and I know I am safe using this extension. The only feature I request is more volume.

Worked fine for me

Simple, clean & free. Works great!
Only thing I wouldn't mind seeing added is +/- buttons to adjust the dB's besides clicking & dragging the slider with mouse.

Edit: Thanks Dev! The many hours on the update is much appreciated!

doesn't work for me, unfortunately

Works immediately to boost volume with no quality loss. Doesn't ask for suss permissions like other add-ons claiming to achieve the same thing.

Works great, individual tabs can have their own audio level, and the only extension with unintrusive permissions. +1

This works very well and all, but there is a very important feature that I have noticed is missing, the ability to save preset volumes for specific websites.
