Can't upgrade Firefox

[Magritte]

I'm trying to upgrade from 2.0.0.1. When I go to drag the new version into my applications folder, it tells me I don't have "sufficient permissions for some of the items." WTH? I'm an administrator (and the only user) on this machine and never had a problem installing Firefox before. Is there another way to upgrade it, or a way to fix this problem?

1, try "check for update" from your firefox 2.0.0.1's "help" menu

or
2, try delete current version first

2, try delete current version first

Uh, yeah, that second one worked so I feel like a big idiot. In my defense I've never had to do that before with Firefox updates. Oddly, in 2.0.0.1 the "Check for Updates" option was disabled so maybe something else was wrong too. Anyway, thanks.

Problem still present...

For some reason, this problem is still affecting us where I work. We have to remove Firefox 3.0 with an admin password in order to update to 3.0.4.

Does anyone have any idea why it won't just overwrite?
