Why when I go to install the new version, does the installer tell me I have a newer version already installed?? Especially because I DON'T!! I have 43.0.2 and this is 43.0.3, so why the confusion? It tells me:

A newer item named “Firefox.app” already exists in this location. Do you want to replace it with the older one you’re moving?

I'm trying to install a newer one, so why is it doing this?

If there a problem 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

Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you uninstall and (re)install 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.
