I'm not sure if this problem affects everyone, but as of this morning, theater mode is broken; whenever it is enabled, you can no longer pause the video, the controls are all finicky, and the sticky video is transparent when scrolling down. Otherwise, this is the best YouTube add-on after Enhancer for YouTube got abandoned.
edit : CSS quickfix resolves the issue

Really excellent extension!! This is the fourth extension that I've tried for enhancing YouTube and I really like this one.

I would love see configuration to make full-screen scrollable where in full-screen, you can scroll down to see the comments/other videos (instead of the 'other video suggestions')

Thank you so much for this extension!!

Edit: I originally had the following issues in my review, but im pretty certain this is a "me" issue with something breaking it on my end, not an actual issue with this extension. I'm leaving it below for posterity's-sake but i dont think its the extension at fault:

~~For the developer, I've noticed a few tiny issues that may/may not be known (and could also be something on my end):
1. For some reason, clicking on the video-space doesn't pause/unpause/fullscreen on double click/etc., I can only click on the interface buttons themselves
2. I have 'Right Click + Scroll Wheel' enabled for changing volume but holding the Right Click doesn't prevent the page from scrolling (see attached pastebin)~~

I'm very grateful for the Custom CSS/JS sections, I've added some small custom tweaks for resolving #2 and making the 'Back to Top' button better for myself. If you're interested: pastebin/BaVNLpss

Very nice to customize YouTube with, but I've run into an issues with the new update causing the video focus and progress to flicker, making it hard to click on the the player buttons, other than that, it's really great, and keep up the good work :)

Brilliant extension! Makes YouTube usable in 2025. Thank you!

Amazing work, thank you!

Lightweight, efficient and very nice add-on, well done! This needs to be more popular

A lot of settings, each one is very easy to understand and works well

A lightweight extension with lots of options. Very high customization options, finally YT doesn't look like a trash can.

Amazing work, thank you!

Great extension!!
One thing I'd love to see is a way to make theater mode on by default when opening a video.

It simply brings back the great layout from 2017.

works great, but recently there has been a clipping issue on the home page, where videos on the right hand side are cut off by a small margin making the drop down menu (:...) to add to playlists or hide videos becomes a little more difficult...turning off the extension fixes it...also have the items per row setting in video grid turned off....

Edit- found the setting responsible...enabling 'fix misaligned videos' in the video grid section or 'dim watched videos' on the homepage section seems to trigger the issue...

What a great extension (the best there is) and thank you so much for repairing the Theater Mode issue.

Better than YT Enhancer & YT Search Fixer combined!🥳
Hope you find a fix for hiding Clip/Thanks/Share buttons soon because that doesn't work right now (they simply get pushed into the (...) menu next to the like/dislike buttons instead)

Good extension. Sadly the theater mode height broke yesterday for me, hopefully can be fixed soon! It goes down lower than it should and the % doesn't seem to change anything anymore.

I initially used this when Youtube changed their grids to have maximum of 4 videos. Which is insane on high resolution monitors. Now I have customized so many things about Youtube with this add-on that it has become quite integral to my usage of Youtube. Thank you for this.

Oh and if you could add different grid setting to Subs tab now that Youtube killed list view, that'd be great.

shitty pointless youtube update completely broke theater mode, I hope the option to change the height can be fixed soon. Other than that this extension is amazing and fixes a lot of their extremely stupid design choices.

Was looking for a replacement for Enhancer for YouTube (now that the new UI partially broke it) and this is the best one I found! A few features it could borrow that would further improve my experience:

- Auto expand into theater mode
- Auto pause background tabs with videos playing when a video starts playing in a new tab
- Universal auto pause when opening video
- Boost volume toggle UI button
