Yes, firefox68 varies significantly from firefox. The 69.0 release was
when ryoon@ changed things to require clang absolutely. When I last used
firefox68 on NetBSD 8.1/amd64 (a couple of months ago), it built and
ran correctly for me without any tweaks needed. I can try it again.

You need clang 10 (in pkgsrc-current). I can duplicate this error with
clang 9. (My test environment was NetBSD 8.2/amd64, with pkgsrc-current
as of mid-May.)
