UPDATE:

I love this extension. When I left my previous review I *had* done something wrong & I wasn't using it properly.
It took me a while to figure out but my displeasure came from 100% user error.

When I use the add on the way it's meant to be used, it works great. I've occasionally come across things that it wouldn't work with but it's been rare.

It's not high tech but it does what it says it does and it does it well.

I use this add on daily & I'm grateful for it.

Previous review:

Either I've done something wrong or this just doesn't work on my computer. It either makes no difference or the difference is so small that I don't notice it at all.

Bummed, I really wanted it to work.

Not working

Works excellently

it works perfect it saved me a lot in some times when the sound of something is too low and i dont wanna install a sus program just to made the volume a little more high, i love it

useful

No sirve con varios sitios (por ejemplo: hooktheory.com).

This extension is excellent and comes highly recommended by me. However, there is one drawback that led to a deduction of one star in my rating. It concerns the process of relocating the sound bar to the next tab, which requires either pressing Ctrl-Shift-6 or navigating through the extension settings. While this task isn't overly difficult, it does present a minor inconvenience. Despite this issue, I still wholeheartedly recommend the extension.

needs improvments..like, rememer volume, show volume number while you increase it...

could be more than 600% especially since it doesnt sound like 6x times higher loudness.

Отлично Работает !

lifesaver

I would imagine 600% to sound harder, but it does help.

Quite nice and useful! Doesn't work on certain cites for reasons probably out of the Add-on creator's control, but is quite useful nevertheless! Good job.

Does exactly what it says on the tin. 👍🏻 Only downside is that I have to reset the volume when playing the next video in the same tab. Guessing it has to do with embedding on some sites.

good

Works exactly how it's supposed to. Click on extensions button (Puzzle Piece Icon)across from your address bar to activate, adjust volume and rate it.
