Netscape would know, when you tried to import it, if it had been

Doesn't seem to be - I do not see anything resembling a checksum in the (FF
v52.5) export file.


There was nothing resembling a checksum in the Netscape file either.
NS detected editing by a different means, not a checksum.

You could not see what NS used in a normal text editor. You had to
open the original exported file in a hex editor and know exactly what
to look for.
