Chosen solution
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.

Hi Fred,
Problem is: it crashes as Firefox is open, so I can't even get one single window/tab open. As soon as it opens it instantly crashes and closes, only leaving the log/quit/restart window.
If you can't get Firefox to open, you will have to do this the hard way. https://support.mozilla.org/en-US/kb/mozillacrashreporter
