Not able to update to latest version, either automatic or manual

已張貼

I am receiving a message to update to the latest version of Firefox . When I attempt to install either automatic or manual, it does not work. I do not have Windows installed on my MAC Air device.

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 63.0.3:

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.
