I download latest version of firefox and when I try to install I get a message that says 'Unable to Update' 'You don't have permission to install it'

Veröffentlicht

My older mac was on the fritz and just got it back from repair. It was rest to an older version of Firefox so I've downloaded latest version but when I try to install it says 'Unable to Update' ' A recommended security and stability update is available but you do not have the system permissions required to install it. Please contact your systems admin, or try again from the account that has permission to install software on this computer'.

What do I need to change in my settings?

thank you!

If there is 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 62.0.2:

Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you 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.
