Unbelievable. The author has dissected YouTube.

The number of features is staggering. There is something for everyone—too much to list in this comment; you have to try it yourself.
Amazingly, every option is explained via tooltips, so you know what to expect. The UI has a clean and elegant style, something that browser addons often fail to achieve. After finalizing your settings, you can export them and easily apply them to any device and browser.

I was using YouTube Enhancer before, which had a fraction of the settings that this extension offers, and some of them didn't even work!
Frankly, the former looks like a joke when put next to this one.

These should be the official YouTube settings, and the author should be employed by Google, collecting big paychecks. This addon simply feels like a part of YouTube.

This absolutely smashes unhook. I found it searching for "make thumbnails smaller" but the more I tinker with it the more features I find that I didn't know I wanted. Even the UI and tooltips are first class.

Lots of options, nice work!

Very powerful tool. Not for dummies, yet.

FANTASTIC PROGRAM. Seriously. I only got it to -ensure- that subtitles stay in the dang lower bottom where they BELONG.

But the quick controls using the mouse (I have enabled in full-screen), as well as the ability to alter the time it takes for the controls to disappear, and having them not appear with any mouse movement but when you actually point in those regions.. it is fantastic. It makes youtube browsing a blast!

Great extension. Have switched from 'Enhancer for YouTube'. Thanks to the developer.

This is the best add-on for YouTube customization!
Especially the sound settings and Clean Player!
Why so few users?

Just recently, I had a problem with my YouTube thumbnails getting too big, and thanks to this extension, I was able to get them back to normal. It works perfectly with no conflicts with other extensions. Thank you for making this!

Superb addon but it lacks some features:
- unround corners of player and thumbnails
- semitransparent gray overlay with text "watched" for watched videos' thumbnails (like in AdashimaaT­ube userstyle) because dimming hurts
- turn on/off codecs av1 vp9 avc (like in Improve YouTube)
- prefer 30fps video track over 60fps, sdr over hdr
- apply audio processing changes only to current video and return to user-defined defaults in next video
- restore old animated thumbnail previews when inline playback is disabled (like in Restore animated thumbnail previews script)
- currently active audio processing options in Video Playback Info
- mirror horizontally in video filters

Works really well. Being able to set a different video resolution for playlists would be great!

works good. please add more features

This addon is a game-changer! It delivers the long-awaited features I've wanted on YouTube, including subtitle search, zen mode, Shorts integration into the regular player, and convenient right-click actions. It's clear the developer understands user needs, as these features are as useful as those in their Video Dominator addon. InzkDev, you've done it again!

Would love to see a overlay feature for the interaction zones. As it's sometimes hard to remember what area does what.

Seem to work good, thank you!
Would you add saturation setting? I need higher contrast + lower saturation, so now if i set higher contrast, saturation gets too high, some times faces are too yellow.
Otherwise would you recommend some other addon that gives saturation tweaking and doesnt interfere with your addon?
UPD Theres saturation tweaking now! Thank you so much!

Now that Enhancer has been left to rot thank you for a viable alternative.
