Don't know what you got til it's gone! Rated 5 out of 5 stars
my FF was crashing so i started eliminating addons one by one to see if one might be causin my crashes. anyway, i forgot to turn adblock back on, and all i can say is "ya don't know whatcha got til you disable it"! Ads were EVERYWHERE, especially those darn floating ads. All gone now when i re-enabled Adblock. the single BEST addon for FF hands-down!!!This review is for a previous version of the add-on (0.7.5.1).
