[Switched due to continued closed source in 2025, but flawless experience otherwise]

Was my main driver for Youtube for at least the last four years and has been flawless in my usage.

Initially I would've given this five stars before, but the software is still closed sourced. Good alternatives now exist with mobile functionality (Android) and extended feature sets while following open source principles.

Thank you for everything, MRFDEV.

the audio boosting makes cheap earphones good, 這個擴充套件很棒，我推薦您使用!

Since June, the app has been causing YouTube to malfunction.

It used to be useful, but then it "required" Firefox 121+ for some reason (though manually copying the files to ESR115 works).

Bugs:

• There's a bug in the resolution settings that hides anything above 720p.

• The speed override has a bug where it only works for the first video in a playlist and subsequent videos revert to 1× speed. If I can't force an entire playlist at 2.5×, then this doesn't help. 😕

Broken. This extension triggers yourtube's adblock detection. I can't watch videos with this turned on now.

Please provide update to Firefox extension also, the extension is only getting update in Chrome. Thanks.

Works great but I am starting to see "web blockers not allowed" when I open youtube. I can close the pop up and youtube works. First time this has happened and I have had the extension for well over a year, probably closer to 2.

esta increible se puede personalizar todo

terrible

Videos on YouTube lag and play at a low fps since the dev has abandoned this extension.

Just post version 3.0 on a git or something. i think mozilla's review process is terrible too. easily a fav addon, but does not work at all anymore.

Addon breaks uBlock Origin; I get the ad-blocker prompt on Youtube unless I have this disabled.
