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

2025-10-04. 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.

Great but lacks autoplay disabling even when it’s not a playlist.

EDIT : answer to the dev : I honestly don’t know how to be more precise. I am talking about autoplay, a well known YT feature.

++ thank you!

The only open-source general youtube enchancer I know, works great

Wonderful Add-On with source code available under MIT License. I replaced "Enhancer for Youtube" with this entirely about a year ago and realized I should probably give it some love. The former is no longer as reliable as it once was unfortunately and this add-on implements most of the same features and just does it better as far as I'm concerned.

A great alternative to the "Enhancer for youtube" that stopped working. The only important thing missing at this time is the popup player that appears as you scroll down to read the comments. Thank you for making this.

I do really like this... However, at the risk of messing things up, I'm actually using two separate "Enhancer" extensions at once, and the other one I like even better. Why then this? Because it's not perfect either, and I think they complement each others nicely. I use Enhancer for YouTube™ as my primary enhancer, I use it for theme, automatic video quality (separate for regular, fullscreen, popup and mini players), and automatic comment sorting, and to add some buttons under the video player - mostly. And then I use this mostly to add more buttons inside the video player. However, if the other one ever becomes unavailable (and it was for a while at one point), then I'll use this one for much more.

Anyway, both are awesome - and I thank you for making this, and even more for making it FOSS!! <3

Great little add-on for Firefox. Still giving it 5 stars despite the playlist annoyance.

There's no setting to disable the add-on from hiding playlists which means no auto-play music. I can disable the add-on, but I still have to restart Firefox to see playlists again.

Edit: Disabling the add-on actually does nothing even with restarting. I wish a setting to view playlists was a thing.

I like your extension thank you, so I have some requests; can you add "Pop-up player" when you scroll down for reading comments need to continue to watch the video..
and can you add "Automatically expand the video player" not just a manual button.
the last one is "Automatically sort comments from newest to oldest" this improvments will be perfect for the extension. Best Regards.

Answer to Developer: Thanks for your response.
"Are you talking about maximizing the player?" Yes automatically maximizing. Waiting for new features.. Thanks again. I wish you success.
