YSK: Here's a list of browser extensions to un-shittify Youtube
Why YSK: Youtube's enshittification creates an abysmal experience. There's a list of Chrome extensions I've collected over the years that each fix an aspect of Youtube to bring back a genuine experience. I've seen in comments people mention one or two of these at a time, so this is a pack that contains everything you could need, and more.
One I use is called "Unhook". You can use it to block different features e.g. Suggestions, video end screen suggestion, front page feed, shorts. It's great if you spend too much time on YT and going on a cycle of watching suggested videos. Now, I only watch videos that appear in my subscriptions or those that I search for.
I also use Better Subscriptions allowing me to hide watched or unwanted videos.
