mozilla-adblockplus-2.6.6-1 shows 2.6.4 installed

[Andre Robatino]

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.)
