Works very well. Highly configurable and maintainable. Great feedback and support. AND, it is FAIR with the Acceptable Adds initiative (up to YOU to support it).
I have to turn ABP off for three out of five sites (for at least the page) I go to, which is annoying, but worse is that the option to block specific items on a page has disappeared and I'm now having to deal with all sorts of crap that are definitely not "unobtrusive" ads!
