Can't update. It says contact admin., but I'm admin?
Every time I open firefox it says to update (and it tries automatically). Each time it tries it says "Unable to Update...."you do not have the permission required to install...Please contact system administrator...etc. BUT--in settings I AM the System Administrator???

If there a problem with updating or with the permissions then best is to download the full version and trash the currently installed Firefox application to do a clean reinstall.
Download a new copy of the Firefox application and save the Disk Image file to the desktop
- Firefox 50.1.0: *https://www.mozilla.org/en-US/firefox/all/
- Trash the currently installed Firefox application (open the Applications folder in the Finder and drag the Firefox application to the Trash) to do a clean reinstall
- Install the new version that you have downloaded

Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you uninstall and reinstall or update Firefox, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
