Very helpful and significant improvement to the Youtube UI. Frustrating that you need a 3rd party addon to be able to adjust the interface in this way, but great job by this author and hopefully it doesn't get removed or blocked in some way...

up right, puzzle icon, to begin tweaking
Thanks a lot Pedro !! amazing add-on

Thanks, works awesome!

I'm completely baffled that I've never come across this extension before. Recently youtube made another horrid decision where you can't hide the annoying shorts anymore which sent me on a searchspree. Finally I came across this BRILLIANT extension that does way more than I ever dreamed of! My homepage FINALLY has a great oversight! No longer will I have to scroll because the video thumbnails aren't the size of football fields anymore! Thanks for this amazing extension!

worked very well, my UI now looks clean, and Youtube shouldnt be forcing dogshit UI's in the first place.

Best add-on ever!

I was pulling my hairs out with this new Youtube UI/UX. This developer is the GOAT, thank you so much for giving us all a fix for this horrible UI change. what were they thinking....

God bless the creator for fixing basically everything wrong with the Youtube UI, especially after they decided to make the thumbnails so large that I could only see like 4 videos on the entire page, and much more.

How does it work? Literally no options on Mozilla, I can't find anything

EDIT: After Dev response, this is a 5 stars. I have 6 videos in a row instead of 3. God Bless

Thanks ! These YT UI changes (thumbnails size) are awfull !! Google is becoming the worst company in the world.

i love you, thank you :3

Found this extension after Youtube switched to the new stupidly giant thumbnails - very happy to have that fixed, and some of the other tweaks look very useful too. Thanks a lot Pedro!

Another tweak that would be useful to add would be removing auto-translations (in general, but especially for video titles in the video grid)... But the separate extension I currently use for that (YouTube Anti translate) is sometimes a little bit buggy, and I suspect this might not be trivial to get right?

Started up YouTube today and the thumbnails on my 32 inch monitor went from around 6 or so per line to 3 per line. So I did a search and it seems this has been happening on YouTube lately and for Firefox YouTube Tweaks was suggested.

I installed it and was able to get the number of thumbnails back to 6 and even was able to increase it more, I settled on 8.

Only thing I couldn't seem to fix was Shorts are still too large, but I may have missed something.

There are also a lot more tweaks like removing shorts, which I have been playing around with.

Woke up to see only 2 videos per row on a 55 inch tv and only 4 when zoomed out to 30% which is just inconceivable that someone thought that was a good idea.
Thank you Pedro you are the goat.
