Very nice, but would be much more better if you can set default volume via settings.

Why did you removed ctrl+shift+V short cut??
I only can give you 1 star for this add-on so far.

When active, YouTube video's speed doesn't work.

It's there when you need it. Works beautifully and quickly. Highly recommend

Excellent. Thanks Aliaksandr !

just works. using it for awhile now.

can we get a icon color change option for us users in Dark Mode ?? it is a black icon thats kind of hard to see

Does the job!

excellent!!!

very good for loud site

Excellent addon

Excellent addon, one of my top 2 addons I use constantly. I can't give 5 stars because of an issue, where if a page has more than 1 embedded video, the addon does not migrate the custom volume to the next video.
Say I set video 1 at 440%, when I open video 2, volume is still set at 440% in addon, but at the volume of 100% through speakers. I have to reset addon to 100%, then back up to 440% for each video.

This add-on worked once and has since stopped working.

it worked right after i installed it on the latest firefox on win64bit '7' .

It doesn't work reliably for me, which is disappointing because it looks like it does for everyone else =( In sites like Twitter and WhatsApp, which don't constantly play sound but do sometimes, I have to set the volume back to 100% and then up to whatever level I want whenever I haven't played a sound in a while. This is without closing the tab or navigating away, and with the icon still showing the higher volume :(
