When upgrading Firefox I get the message, "An older item named “Firefox” already exists in this location. Do you want to replace it with the newer one you’re moving?". Choosing YES results in "Operation can’t be completed because item “Firefox” in use."

Using Mac Snow Leopard 10.6.7 Current Firefox: 3.6.18 Trying to update latest version: 5.0.1

This seems quirky. In Updating a newer version of Firefox is should seem obvious that the existing firfox executable would be replaced by the newer version ?!?

Thanks for any help you can give.

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

  • Trash the current Firefox application to do a clean (re-)install
  • Install the new version that you have downloaded
