I'm one of the people still using Firefox 3.0.20 (last version of the now obsolescent 3.0.x series), due to not yet taking the time to see if all the extensions I use are still compatible with more recent versions. ArgyllCMS XYZLUT+MATRIX display profiles work with that old version and use the XYZLUT part of the profile, tested with the GBR swapped matrix version of such a profile. Embedded version 4 ICC profiles also seem to work, at least the examples on color.org I just downloaded the portable versions of Firefox 3.5.9 and 3.6.3, and tried them out with the same swapped matrix version of the XYZLUT+MATRIX display profile: they both display images correctly using the XYZLUT part of the profile. (I used http://foto.beitinger.de/browser_farbmanagement/farb-testbilder.html as a convenient source of color patches photos with various embedded profiles; I also used the special test ICC profile available on that page to convert a photo's colours: the result displayed correctly once the test profile was embedded.) Side-by-side comparisons of photos in 3.0.20, 3.5.9 and 3.6.3 browser windows showed no significant differences with gfx.color_management.mode set to 1 in the more recent browser versions (i.e. all graphics are colour managed and untagged images are managed as if in sRGB, which is the default with 3.0.20). But I didn't spend too long doing these tests--caveat lector. These recent versions still cannot deal with version 4 ICC profiles, at least those embedded in test images on color.org. So there seems to be progress on the new Firefox CMM--it began as a rapid cut-and-paste affair out of LCMS (according to the relevant Bugzilla bug report, whose number I've forgotten), but it has evolved.
