Hi Ben, You can take a look at the folder /Program Files (86x)/Mozilla Firefox/Profiles

And there right click and click properties. Make sure the folder permissions for the system user is Full Control

guisg2, thanks, but I'm having trouble finding the folder:

Program Files (86x)/Mozilla Firefox/Profiles

Can you pls tell me how to find it? Ben

Sorry, both the answers posted here refer to Firefox on Windows. The system information posted with your initial posting here indiscates that you are running Firefox 13.0.1 on Mac OS X 10.7.

Is that correct?

Or are you posting from that Mac about an issue with another computer?

Yes There is an addon called : open profile folder. https://addons.mozilla.org/en-US/fire.../open-profile-folder/

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

• Firefox 30.0: http://www.mozilla.org/en-US/firefox/all.html

• Trash the current Firefox application (open the Applications folder in the Finder and drag the Firefox application to the Trash) to do a clean (re)install
• Install the new version that you have downloaded
• https://support.mozilla.org/kb/Installing+Firefox+on+Mac

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.

I'm using Mac OSX10.7 Trashing the app and dock icon worked, clean install, perfect. Thanks!
