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.

could you add functions to tweaks how many shorts and posts per row (with options like max number and min width)?

The other day my YT started showing only 4 videos per line on a 4k screen set to 2560x1440, with even more space available if I wanted. I jumped onto Reddit and found this. It didn't work at all and gave up. But today I decided to look again and saw that Pedro released another version and recognized that YT had changed something fundamental. With that it is all fixed. I set it to 6 icons per line just like it was before YT "fixed" things. I'll have to explore the other settings too, there were too many to get through.

Honestly this is such a fantastic extension, one gripe though and hoping for QOL change, hopefully you can give us the ability to be able to move the popup player with just dragging and grab the corners to resize as well.
