Just testing this as part of the Ghostsurf Platinum 2005 suite, and getting some very strange results. The first thing is it will only work if you are browsing anonymously using Ghostsurf which I find quite annoying as the majority of the time I don't need or want to surf anonymously. Secondly, and more importantly, according to the software it is blocking pop-ups on sites where I know there aren't any pop-ups to block! On one such site Ad-Armor announced it had blocked an incredible 47 pop-ups, yet if I go on the same site with just Firefox blocking there is no report of any pop-ups which makes sense because there aren't any! Oh and in case you are wondering, when I hit the Wilders site, Ad-Armor is claiming to have blocked 2 pop-ups here as well. Make of that what you will.
