I also see this problem, on Debian 10 buster, after upgrading to FF 68.

But what I found strange is that I did the upgrade on two different
machines, and one survived: my laptop doesn't have problems with
uMatrix, as far as I can tell.

Note that this bug also triggers #916594 which means it's impossible to
restore from backups.

That said, the above "rm + cp" workaround *did* work here,
strangely. Not sure what I have different from pabs...
