I am trying to update from Firefox 3 to 4 on my desktop. I did it on my laptop. When I try to drag 4 to my applications folder I get a message saying "The operation can’t be completed because you don’t have permission to access some of the items."
I cannot install Firefox 4. I think I already gave as many details as I have in my question.

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
- Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
- Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
- Trash the current Firefox application to do a clean (re-)install
- Install the new version that you have downloaded
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.
