There was only one entry for a flash player in Firefox's Addons menu.
I tried deleting the second entry from the pluginreg.dat file; no joy.
I'd saved the file as pluginreg.dat.old first; I retrieved it and
deleted the first entry, then saved as pluginreg.dat and tried again;
no joy on playing apps, but loading pages with Flash movies no longer
causes Ff to crash.

Incidentally, that one video I found, (the advert), still plays in a
diminished, YT-like window, although actual YT videos still only show
up as black boxes.

Dimitris, your patience through this ordeal has been an inspiration.
Is there anything else to try?
