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

Moves the live stream chat below the video in theater mode, can't fix without disabling the add-on

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

Amazing addon, this + uBlock Origin makes Youtube usable

Muy bueno, me encanta 👍

this extension is truly amazing for what it does but the most annoying thing about it is the pop-up player that shows up when scrolling, when on fullscreen the scrolling doesn't activate the mini player at all.

I wouldn't want to use YouTube without this extension again, but it's so frustrating that around once a day, parts of it will just stop working. The only way I've found to fix this is to clear cookies both YouTube & Google, and sign in again. This fixes it for another day.

This is a great add-on for firefox. However there are features that can be added and I can't believe they haven't been added years ago. For example, I need an option to check if closed captions are enabled and disable them. Often times I use youtube without being logged in and closed captions are on by default. It's so annoying. Right now I can do this by using a script I found on some website. Also an option to organize comments by number of replies and number of likes would be nice. There is only 1 option to organize comments. Newest to oldest. More options to organize comments would be great. Thanks.
