i keep getting a "firefox update was blocked" notice. ''something has blocked firefox from updating'' i've checked as much as i am capable of to no avail. under ''help/about'' i notice that i am running the most current version but still get these failed updates. i am running 5.0.1 whenever i get this notice, i reload firefox just because and still get these notices. i am running Trend PC Cillan. i have no proxy settings.
