Does it's job with the simple pre-made blockers. If you want customization, ohhhhhhhh buddy you can do anything you can think of. If you have problems they are Quick to get it fixed, if possible.

Breaks Paypal Mastercard site. I've been trying to figure out what was causing a spinning circle arrow and never loading the page til it times out. Finally did, tested multiple times with it on and off and most definitely breaking this connection when you click in the Paypal account to go to Paypal Mastercard/Synchrony website. Just plain works fine with uBlock off, and not at all with it on. Have to disable it til the developer finds a fix.

It does its job perfectly.
