This all seems like a lot of trouble!
Why not just put a Firefox shortcut in the task bar? Simple. Guaranteed to work since 1995.

It seems the problem may have been self-inflicted by modifying default settings in Indexing Options. We'll see.

If so, the search index won't generally reflect the start menu- a more general problem than just FF.

Yes. When it is in the user's personal Start menu. By default only the 'all users' Start gets indexed.

To find out which Start menu holds the shortcut, click Start, find the app and right-click on it. Select More > Open file location. If you end up in C:\Users\yourname\AppData\Roaming\Microsoft\Windows\Start Menu\Programs then it's on your personal Start menu.

To add this location in indexing, look for it under Users.

Notice what you said in your post #12..

start menu is listed but not users

Yes, and just ticking Users in indexing isn't enough because AppData is specifically excluded. You have to go down through the folders list and tick...
Users\yourname\AppData\Roaming\Microsoft\Windows\Start Menu\Programs
