I don't believe updates count. I remember reading that only downloads will be counted and updates to the new version will not. So if you are planning on taking park I guess you have to uninstall the current one first, pretty lame..

If an existing user is forced to remove FF2 first (or to install FF3 next to FF2), it is still an update from version 2 to 3. The internal technical details are not important. It is still just an update (like XP SP2 to SP3).
