I have a mid 2012 MBP with Retina display. When I try to install Firefox upgrades i Get the message that teh update will not be installed, are you running more than 1 copy of Firefox. This occurs no matter what I try even from a restart. Activity monitor only shows one copy of Firefox running

I reset Firefox to the default and that did not help, I started in safe mode and that did not help.

Hi mike_bauer

If there is an issue with update or permissions the better, quickest and safest way is to download and install firefox:

1. Download a copy of the latest firefox from http://www.mozilla.org/en-US/firefox/all.html

2. Trash the current Firefox application to do a clean install.

3. Install the version that you have downloaded.

Do not select to remove your personal data, your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks or other personal data.
