It was in /usr/pkg/lib/firefox/libxul.so if memory serves, so
should be firefox itself.

I'll try a rebuid with CFLAGS+=-mstackrealign.

OK.

I have the build host for firefox on i386 which has a Xeon E5335
CPU (cpuctl outputs from the build host and the T60 attached
below), and where I can run firefox with a remote display to this
T60 laptop, and firefox will actually run.  However, you only get

related to WebGL, while the console log when starting firefox
locally on the T60 is chock full of

and similar messages.  I wonder: is there something which only
causes the SIMD code to be executed if we're on a local display
and/or with GL enabled?
