Absolutely essential. Can't live without it. It's so good, I contribute every year, too, just to help keep them going! You should consider doing so, too! I love the "Zero Tolerance" policy for ads. Puts the power back in MY hands as a user, as it should be.

So cool

So far its working like a champ..

This add-on is great and it works fabulously. I love it and I cannot be more please with it.

ok five star

I very like that extension, it's blocked all my ads, very very like it
