Does Firefox 3.5 support only some ICC profiles (AdobeRGB, sRGB, e.g.) or all ICC profiles in color management?

I put one image embedded with a ICC profile with D65 as white point, and the same image embedded with another ICC profile but with D50 as white point (the 'chad' matrix in the profile is different as well, given different white point for two profiles). When these two images (of same RGB values) but with different ICC profiles embedded are displayed side-by-side in Firefox, difference in color should be noticed between two images if color management is available in Firefox (color management is turned on in about:config). However, I did not see any difference. I tried using the same image but embedded one with sRGB profile, and the other with AdobeRGB profile. Now I can see the difference.

So my question is whether Firefox can only recognize a certain number of ICC profiles but not all of them.

Thanks.

See https://developer.mozilla.org/En/ICC_color_correction_in_Firefox

Caveats: The new QCMS color management system introduced in Firefox 3.5 currently only supports ICC version 2 color profiles, not version 4.
