New user of a few days and loving it so far. Has practically every option I've wanted for YT. No issues yet.
A Lite version for music.youtube would be great, but that would be primarily to handle glitches with the video feature.

doesn't force the theater mode

When the aspect ratio of the video doesn't match the aspect ratio of the screen, the thumbnail is visible through the gaps in the fullscreen mode.

Excellent Extension for YouTube viewing. Has just about every feature you can think of - some of which I'd never considered needing until seeing the option. Would highly recommend to anyone who spends a lot of time watching YouTube.

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.

The only reason I won't make this a 5, because the "reverse order" button no longer appears on the player even despite me enabling it. If this issue is fixed or troubleshooted, I'll rank it 5 stars.

The color customization, volume boost, and speed controls are my favorite features. The customizable control bar thing is great, but it doesn't show up on live videos, playlists, or any video playing in the mini player as I'm scrolling the homepage. This app could be amazing but it needs improvements.

The “Enhancer for YouTube” does not work for my main Google account only.
Sub and spare accounts seem to work 100% of the time.

メインで使用しているGoogleアカウントだけ "Enhancer for YouTube"が動作しません。
サブと予備のアカウントでは100%動作しているようです。

Hey admin, YouTube has put 'Save' button (Watch Later) below those three columns (•••), I wish that button to be as a standalone next to Thumbs Up/Down, please - then it's 5/5.

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
