JoeSimmons / YouTube Auto-Like Videos

And I went to the Greasy Monkey link that were in the other issue post, and it's not working either, seems last updated 2015. I would really like this script to work, doesn't need to be any fancy. It could either auto-like ALL videos(unless I dislike of course) or just auto-like youtube channel names in a list or something.

Looks like I have to make Chrome my default browser again just to get the addon it offers, which sucks.
