The -ax key means that a LUT-in-XYZ-space profile will be built.

It's possible that the Windows didn't know XYZ-LUT profiles at all. It only 
accepts the matrix and Lab-LUT profiles. IMHO.

Just try -g or -s keys for colprof. The profile will be shaper&matrix in the 
case and FireFox will handle such profiles well.

I think there no problems in Argyll.

It looks like the Profile Maker do the matrix&shaper profile. Not a LUT-profile.

The type of profile You try to build is not an appropriate for the case. Try to 
built a simple matrix profile.
