This doesn't look like it actually does anything. There's a light/dark toggle switch and... that's it. There are no settings. If you click the extension, it just goes to a 90s looking webpage. Nothing on that page actually does anything. Hell, the GPU info button yeets you do a google search for "best graphics cards". What the hell is the point of that?
This is one of the most confusing extensions I have ever seen.

The extension is a great idea and adds a lot of very useful features that work perfect. However, the extension constantly makes annoying popup windows begging the user to check out new features of the extension, show ads, or update their browser. This is highly disruptive and abusive and is unacceptable.

Uninstalled. I discovered and installed Enhancer For Youtube instead, which has all the same features and more, without being a spammy piece of malware.

This extension make YouTube slow and laggy

This Magic Actions for YouTube really works,I highly recommended it.

can not get to setting no matter how may time i click the options... firefox is doing and chrome has bee ding it since the setting went to online not local oh and it will not say it's on firefox

updates have stopped. moved to Enhancer for YouTube

Chrome got an update. Will there be an update for firefox too, so that the setting page will work again?

At the momen, the addon is nearly useless for firefox cause there is no way to access the setup page?

Когда то было лучшим расширением.
Где настройки, умники?
Сами себя переиграли, эпитет.

It used to work perfectly and was one of my favorite add-ons. Now you can't access the settings and it is glitchy. The whole website does not seem to work in FF. Support is non existent.
