I have mozilla-adblockplus-2.6.6-1 installed in F21 (was just pushed stable in F19, F20, and F21). Firefox's Add-ons/Extensions still shows 2.6.4, even after quitting and restarting Firefox, and removing and reinstalling mozilla-adblockplus. Do other people see this? (I'm guessing it happens in all browsers and is Fedora-specific. I don't see any mention in the Adblock Plus forum.)
