I halted the building process and did as you suggested earlier.  There
were indeed a number of inconsistencies and corrupted files when I ran
fsck in single-user mode.

I re-installed Firefox using pkg and I successfully launched it.  So
far so good.  I'll keep an eye on it, though I might try continuing to
build it via ports.

One thing I didn't mention earlier was that, before I had the kernel
panics earlier today, each time I tried starting FF, I had to reset
everything.  Evidently, some of the preference files had been
corrupted but either couldn't be restored or would be damaged each
time I ran it.

Then again, considering that today is Tuesday the 13th....

Thanks again.  I learned something new.
