Whenever you open Firefox, Enhancer for YouTube™ sets a youtube.com cookie.

This used to be excellent. Doesn't work at all on MacOS lately. Seems to work fine on my Windows 10 installs.

When this add on is applied, with video enhancement, the images have low frame rate, this is not an issue with Youtube in Edge, or Brave, or Chrome. It seems the speed doesn't work properly with Video filter addon in Firefox, I like colorful videos with speed but speed causes video to become somewhat blurry or slow processing. And support isn't there.

The latest version redirect to random community post when trying to click a video. Temporary solution : downgrade one version

Use to be an excellent app and I used it alot in the old version. Because I am hard of hearing it was excellent because I could turn the volume up just so my hearing aides can get the sound.
However since the update, it is gone from excellent to poor. Bring back the old version and I will give it a better rating. By the way I do use the CC, but not all of the videos on YT have them. I want want my old enhancer back!

latest update is horrible...

Arruinaron por completo este addon. Una pena.
Regresé a la versión 2.0.101. Como hago para que no se pueda actualizar ?

lmao my original review "mysteriously" disappeared, so I'm lowering the score. The addon itself is good, but as I stated in my original review I wish there was an option to revert back to the original UI

Horrible new update, can't even remove that new three dot icon they just added to the Youtube player. By default, this add-on is bloat; you'd be astonished by how cluttered your Youtube player will be if you don't tick off UI options in this add-on's preferences.

has likely a memory leak. let my pc on over night (a single youtube tab) and firefox filled the entire RAM of the PC. removed this addon and now the problem is gone

Enjoyed this; the last update with this moving envelope symbol that cannot be removed is unacceptable.

Why did you have to change the interface? It's terrible.
1. Can't change speed when rolling down to comments, cause the control button is now on the player itself.
2. The loop feature is terrible. Have to manually type in the numbers - when you do, youtube registers it as some hotkey instead and doesn't type in the time. You have to copy paste the number in to the field instead. The slider was much more convenient to use.
3. Autoplay seems to constantly be on, which is annoying.

Edit
Luckily there are older version: https://addons.mozilla.org/en-GB/firefox/addon/enhancer-for-youtube/versions/

Terrible pseudo-update.

The recent update is the worst one in UI
