I use this extension whenever I'm on YouTube. It allows me to control and tweek options so YouTube behaves and appears how I like it. It's a great extension, even though my review is written poorly. Try it and you likely will like it too.

Super easy-to-use extension which does exactly what it says it does in the most user-friendly way I could've possibly imagined. The only question I had after using it for a little while is where I could donate a tiny bit of $ for the creator. However, there's clearly no place for that on the website or via the extension itself. Clearly just a functionally relevant and perfectly designed app created out of the goodness of someone's heart. I consider that a solid win for Firefox users and a tiny victory for humanity as a whole.

EXCELLENT ..... WEBSITE

A great replacement to "Tweaks for YouTube" from the Chrome extension library
