EDIT:  There is data stored in webappsstore.sqlite in vanilla Fx, if 
it's allowed.
The sqlite viewer I was using - http://sqlitebrowser.org/ - doesn't 
display the contents of <my> copy of that file.
It apparently displays some other Fx sqlite files OK.  Dunno.

I know Mozilla has an addon sqlite viewer & I've used it, but would 
prefer a stand alone, as it's seldom used.
Don't need another addon, potentially causing probs, used once in 3, 6 
or...? months.

If anyone has a better suggestion for a free viewer, preferably 
portable, I'd appreciate it.
END EDIT.
