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.

I've been using this extension for years for the custom keyboard shortcuts, and am now putting the comments in the sidebar and scrolling through them as I watch the video, along with browsing recommended vids the same way. Also, you can disable auto play in playlists. I freaking love this extension.

very customizable and helpful, can remove/blur the things I desire to not focus on

Such an absolutely great extension, and completely baffling that it has so few users. As opposed to the most used youtube extensions, that one is fast, not buggy and has plenty of features (the most used lacks the latter, the second most used lacks the two formers). Thanks so much: you made youtube really more usable!

Edit: first problem I've had is it doesn't remember going into theater mode so well, so I've had to add the extension Theater Mode for YouTube. It'd be best if Tweaks for Youtube could do that well on its own, but with that added extension, it's OK.

Edit 2: thanks, I was convinced I had it checked, but I must have had it mixed up when playing with the settings- works great when checked, as you said!

I found this after someone mentioned it could stop the scroll down annoyance with space bar scrolling on youtube (set the keybind for pause to space in this to fix it). I thought I would need to switch to chrome but was glad to learn that is not the case.

thanks to incompetent people and apple products(?) and the lack of monitors or headphones for sound mixing, we get artificially boosted low frequencies - for that alone, this extension is worth installing in your browser. it would be great to expand these settings to individual channels. the second best thing is that this extension doesn’t make page rendering in firefox freak out!

12/10.

Best Youtube tweaker addon

Just want to say this extension is incredible. There's an unbelievable amount of features that are so useful, I love it.

That said, the last few weeks I've been getting MAJOR slowdown on YouTube while this extension is active. Any buttons presses or inputs are delayed, sometimes by a full second or more. The issue is alleviated by restarting Firefox but after a couple hours it eventually comes back up. Totally possible it could just be something on my end but the fact that it only happens while the extension is active makes me think it could be a more wide-spread issue.

Still giving this 5 stars because it deserves it, but I wanted to bring that up in hopes that the developer will see it and check it out.
