As you may know youtube recommendations are the new type of cancer.
Thankfully with simple css we can get rid of it easily.
I use stylus extension to apply this css to youtube results. Easy and simple.

I know It is not perfect but it is very good. It removes the most of the recommendations and the stupid shorts too. Top of that it shows lots lots more result without scrolling that saves tons of time as well.
Enjoy using.
