OK

Addon works as expected, but appears to be injecting it's functional JS into any and all WYSIWYG editors on page. For example, if you have this plugin enabled while editing a page in WordPress, this addon injects it's javascript into the text field. If you save and reload, the script is injected again, over and over.

Once this issue is resolved, I'll update my review.

working without issues

doesnt work got earraped countless times

Does what it says on the tin, and does it well.

It works

the audio level gets enhanced but it feels more like 1.5X instead of 6X

Exactly what I was looking for! Add some extra volume to my videos

I am very grateful for the free use of this great add-on. I have some revisions that you may like.
1) ACTIVATION of ADD-ON, CTRL+3, should ALSO work in FULLSCREEN.
2) When opening new TABS, option = A) open TAB with AUDIO reset to normal. B) open TAB with the "600% Sound Volume" add-on setting, that was previously used.
---> Presently, option "A" is default and is not optional. (Having an Option "B" would be my choice since I run the "600% Sound Volume" add-on, at 300% for every TAB, to match the output levels of my computer, with the input levels required by my external sound system)
---> EDIT: It's 8 months since I made these suggestions, to my knowledge, there is no evidence that they even read my suggestions, let alone implement them. Those changes are simple, I think I'll see if someone else has that feature.

its very nice

exactly what it says on the tin
