I was just checking my own website and noticed that Adblock Plus v1.9 blocked 13 ads on one of my pages and another 4 on one other. This is interesting to me because I have no ads on my site.
I'm running Chromium v43 and have my own web host.
UPDATE: I just checked my sites and now its blocking one ad on one and none on the other. This thing's counter is either haywire or was possibly blocking ads that followed me from a previous site.
On a side note, sometimes it will block approx. 50-60 ads on any given YouTube page.
