i've never been one for add-ons or plug-ins for my browser. (my philosophy with mozilla has always been "if it ain't broke, don't fix it.") i've never even used ABP because i keep an extensive blacklist of ad sites in my hosts file which blocks a large majority of ads already, so ABP isn't really needed. but i just installed NoScript 2.3.9 a couple days ago, and i'm loving it. no more maxed out CPU just to view a page... even wiziwig loads quickly and easily now by blocking scripts from google-analytics.com and addthis.com.
sure, it breaks 90% of sites because they all run a multitude of scripts these days, but most of them are ad-related anyway--so who cares! two thumbs up.
