I updated my OS X to 10.11.6 recently. Firefox is dead. I attempting to install an update as instructed on Mozilla. Does not work. I tried the “enterprise” version, too. It doesn’t work. Tried to recover via Time Machine - since it was system update that didn’t work, either. I’ve lost all my bookmarks. WHAT can I do? Sending using Safari 11.2 since FF is dead.

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.
