Every time I try to download the newest version of Firefox on my mac I get the following error:

"The operation can't be completed because the item "Firefox" is in use."

I close out Firefox and still get this error. I've tried this like 100 times and can't figure out how to fix it. Help!

I have Mac OS X v. 10.6.8

Download the full Firefox installer and save the file to the desktop
https://www.mozilla.org/en-US/firefox/all.html

If there are problems with updating or with the permissions then best 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 application and save the disk image file to the desktop

Your personal data is stored elsewhere in the Firefox profile folder, so you won't lose your bookmarks and other personal data when you uninstall and (re)install Firefox.
