If you hate web ads and like individual control over what gets blocked and what doesn’t (there’s tons of granular control here), this ad blocker is the best I’ve used. I had previously purchased the iOS version, and when I found out a Mac OS X version came out, I jumped on it.
Bonus: icloud integration synchronizes all your settings and customizations across platforms!
And because it uses the modern version of ad blocking technology (via Webkit), it’s much faster (saves on webpage loading time) compared to the traditional Safari ad blocker extensions.
P.S. No, I am not paid by, nor am I related to the developer. I just think he’s made excellent software that does what it should, and does it well.
