I use a combination of add-ons to fix YouTube that let me:

* Block shorts

* Adjust the number of thumbnails per line, thumbnail shape, border, etc

* Limit the length of titles/descriptions

* Force titles/descriptions into normal upper/lowercase

* Change the default player window size

* Show thumbnails actually in the video (from start, middle or end)

* Fix literally dozens of other annoyances

For Windows desktop under Firefox:

* "Nova YouTube" https://github.com/raingart/Nova-YouTube-extension script running under ViolentMonkey add-on. Nova YouTube is framework that puts modular YouTube fix scripts under one UI.

* "AdashimaaTube" script running under Stylus add-on.

* "Enhancer for YouTube" add-on

* uBlock Origin (of course)

For Android phones: Revanced Extended

For Android-based streaming sticks: SmartTube

Note: The set of add-ons & scripts I use in desktop Firefox is just what I happened to end up with at the time I finally got fed up a few years ago, looked for solutions, tried out several and settled on this mix as working for my needs and preferences. YouTube is constantly changing (usually for the worse), so the landscape of community add-ons and scripts is constantly evolving in response. You'll probably need to update to latest version on whatever solution(s) you use at least every couple months.
