There actually is a Firefox bug about this problem here:

Bug 509710 - qcms doesn't support profiles without tone reproduction curves
The other day I attached a Argyll XYZ LUT profile to the bug, and made the
comment trying to confirm if qcms in firefox really does support XYZ LUT
profiles.
@Everybody who cares about Firefox 3.5's lack of support for Argyll XYZ LUT
profiles.
In case anybody is unaware, this problem arose from Mozilla deciding it
wanted to write a new color management system from scratch, QuickCMS (aka
qcms). Unfortunately qcms is currently limited in features & profile
support, not as accurate as lcms, and still a work-in-progress. The
work-in-progress part is good in a way since eventually (if eventually is 10
days or 10 years who knows...), it's features and support should be flushed
out. This of course depends on developers willing to write and commit
patches in a timely fashion.
If you don't feel the need to use the latest Firefox 3.5, use Firefox 3.0
instead. Firefox 3.0 uses the MIT Open-Source project LittleCMS (a.k.a. lcms
| http://www.littlecms.com/ ). lcms is a full featured cms system and it
supports Argyll LAB and XYZ LUT profiles, ICCv4 profiles, as well as pretty
much everything else under the sun, in a much more accurate manner then
qcms. Mozilla claimed they had their reasons for ditching lcms (something
about security?) but it made me a little annoyed when they did so.
That said, Graeme, I still hope you would consider looking into adding
matrix tags to the XYZ LUT profiles like other profiling applications do, if
it really doesn't turn out to be too difficult.
Thank you.
