Does what it says on the tin, and works well. But I wasn't able to adjust Playback Speed on YouTube after installing. I uninstalled, and was able to adjust it again. Not sure why it's interfering.

Very good addon.

I love it and it works as it should, but I would like some more shortcuts (200%, 300%, or custom), and maybe a way to make it always on for some websites?

Doesn't work on sites like Bandcamp and Soundcloud

Just an amazing Add-On...Works amazing on YouTube....Big Thanks to Developer

VERY helpful! Great f/pages' low audio. One request - ability to set DEFAULT increase. Reason = if problem is consistent (ie. SPEAKERS), then have to increase f/each & every page separately.

1000% POWERFUL ADD-ON!!!

It works really well. The only thing that I noticed and is a dealbreaker for me is, that speeding up or slowing down videos doesnt work anymore. If that will be fixxed, it will be flawless.

At start, it reads 100% but it's lower than 100% w/o app. It Lowers max volume on system unless you use app to increase. Then you get higher max volume than without app though 600% is at best 300% actual increase. You have to re-increase volume on each and every page or app you use. needs higher start volume or have preset for at least 200%. I under stand why they don't have preset, because if you have a web page that has extremely low volume and you increase to 600% the go to page with high volume and your on 600% there goes your speakers.

wonderful, only improvement would be a way to preset so that I did not have to adjust every time I open a new webpage.

It's good but:
- doesn't save the setting (need to reapply each time a new episode starts in netflix for example)
- doesn't work with other extension such as alternate player for twitch tv

Literally works, and even better you can go lower than 100%
