My go-to ad blocker. Love the content picker as well.

You Are So So Awesome !!

Good for blocking useless ads!

It is the best and first add-on I install when I have Firefox installed.

I would recommend everyone to read the wiki about uBlock Origin's blocking modes and arkenfox's recommendations.
