This is usually worked around with -mstackrealign. Firefox sets that in
CXXFLAGS for i386 but not in CFLAGS. Adding CFLAGS might be worth a shot.
Could well be in a 3rd party library somewhere else in pkgsrc though.

Mozilla still supports it but there is not much coverage in terms
of pkgsrc users so run-time breakage is to be expected from time to time.

That said tsutsui@ posts screenshots of Firefox on NetBSD/i386 on X
(fkas Twitter) every other month or so. Most recently firefox-120.0 on
10.0_RC1 last month.
