Seems to do all I need but the behaviour is inconsistent. I had it configured how I wanted and the next day all my setting had reverted. Then, trying to add the screenshot and volume boost buttons to the bottom of the player removed the existing fullscreen, minimize and settings buttons, and the new buttons were misaligned. Good but needs work.

FINALLY a way to get rid of those AI summaries!! However I don't know if it's just me, but that only works when I uncheck and then recheck the box while on the video page, otherwise the summary still shows up. In any case, still a great extension, with many features I didn't know I needed until I saw the whole list haha

Awesome plugin, it would be nice if we could get the restore old UI like how the discontinued Youtube Enhancer works in Chrome, I just noticed today when trying it automatically restores the old UI. Also just that and an option to pin the player when scrolling down with adjustable sizes and different positions, just like in the old discontinued one and man this plugin will be NUMBER 1!!! Now I have to just use like 5 different plugins and combine them for the features I need but hoping in the future I can remove a few and only use this one and a few others perhaps instead of 5 plugins and 2 tampermonkey scripts. One script to restore old UI ofc and few others. Thank you so much for your work! Hope youtube doesn't remove their old UI fully too soon or I'm gonna be annoyed lol ah well. I'm sure people will be able to re-create it somehow with css theming or something I hope. I cannot stand this new UI will always figure a way to replace it. One last option I think could be added to your plugin is restoring the smaller icons only in theater mode, instead they use these bigger icon versions. Maybe this ublock filter could help you implement this feature itself. Fix the wwwdot i cant send links in FF review's.

uBlock filter: !Sep 8, 2025 wwwdotyoutubedotcom FIXES BIG UI IN PLAYER WHEN SET TO THEATER MODE - YOUTUBE

Отлично работает, все свои функции выполняет. Не хватает только 2 вещей: отключения автовоспроизведения и возвращение старого режима театра, новым пользоваться невозможно.

Appreciate the awesome add-on—thanks a lot!

Thank you for making this, finally let me remove Youtube shorts. I have lost so much time because of them and their constant existence was an endless reminder and temptation for that sweet instant dopamine followed by a deathscrol until I would recover 30 minutes later.
I can hardly describe the sheer relief I felt when I saw them disappear from my screen in real time.

I don't even know if I am going to be using a single one of the other features but dear god does the shorts being gone feel like freedom.

Very good replacement for now old and removed Enhancer for YouTube.

Great replacement for the now defunct Enhancer plugin, with some additional customization which has been quite nice. Although it took a bit of time to figure out why I couldn't figure out why I couldn't place some buttons.

I've been using this for awhile now, how long? I don't know but there wasn't many reviews when I decided to use it. I just wanted to leave a review now and while I can't say anything about a lot of the features since I don't use them but the ones I've been using have worked with no issues and been perfect for my use of it; which is mainly the loop button, automatic quality setting and volume boost. I've been testing the themes recently though and I've liked them. Thanks for the extension and the work you put into it VampireChicken & everyone else! :)

Does what it says out of the box. Alot of options and functionality. I chose this to replace "Enhancer for Youtube" after it disappeared from the addon list

Unfortunately unusable with the dark mode themes. Since they force black font and you can't read black font on a dark background. Can fix with custom CSS, but you shouldn't have to. You also can't edit the specific colors for each theme, which makes me wonder why they even show the color options.

works perfectly 10/10

2025-10-24 Update. Latest version 1.29.0 also not updating. Still no error msg on update. Thinks its updated it, but re-checking updates puts it back in the update list. Guess its the same problem with Firefox 115.29.0 esr (64-bit) version *since updated from 115.28.0 used previously.
Any update on a possible fix please?

2025-10-04. I'm using Firefox 115.28.0 ESR for Windows. I'm getting an error...
I'm using 1.28.0. "Available Updates" will now show 1.28.1 but won't install. No error msg.
Exported settings and Uninstalled 1.28.0.
Install latest version 1.28.1; Mozilla says file is corrupt. File: youtube_enhancer_vc-1.28.1.xpi.
CRC32 = df3dda8d.
Github .zip same error on install. SHA-256 verified the same.
Reinstalled 1.28.0 OK but restoring settings failed to work. No error msg.
The "Available Updates" will now show 1.28.1 again but won't install. No error msg.
I’m using Windows7, so it’s Firefox 115.28.0 ESR for me.
Guess it’ll be Linux after that because Win10/11...omg, what have they done!
Thanks for replying anyway.

Adds tons of new functionalities and changes YT's behavior to suit what I want.

One caveat - with the latest version, blocking YT Shorts doesn't work correctly anymore. This is the option that made me install this add-on in the fist place, so I'm hoping it gets fixed as soon as possible.
[edit] After reading the author's reply, I updated Firefox from version 143.0.1 to 143.0.3 and it indeed started to hide shorts as expected. Perfect!

Dev even added a feature I requested. I really have to read the description of this extension to even know what it does - it's all natural for me now. I install this each and every time.
