Here there are done many tests related to this bug written 2013 and still buggy: https://www.metalvortex.com/blog/2013/01/12/1115.html I have the same issue when using x-rite profiles out of colormunki with ICC-v4 enabled. New x-rite software i1Studio do no longer support v2, so I have no choice workaround with v2 instead of v4. Maybe because x-rite uses all specs from ICC-v4 (LUT, matrix). My profile is tested and well done, but not working only in Firefox (all versions till 57). Here upper 2 quadrants are dark blue on first picture: http://www.color.org/version4html.xalter Here first 2 bars are ok cyan/white, 3rd ist black (or very dark blue) and white instead of purple/white, 4th ist ok purple/white: http://cameratico.com/tools/web-browser-color-management-test/ For test on your system you can load ICC-profile from here and see the 2 pages above: https://bugzilla.mozilla.org/show_bug.cgi?id=722831 https://bugzilla.mozilla.org/attachment.cgi?id=593201 This case or similar ones are reported many times but never solved: https://bugzilla.mozilla.org/show_bug.cgi?id=791456 https://bugzilla.mozilla.org/show_bug.cgi?id=1375423 https://bugzilla.mozilla.org/show_bug.cgi?id=679876 https://bugzilla.mozilla.org/show_bug.cgi?id=852241 https://bugzilla.mozilla.org/show_bug.cgi?id=1204423 https://bugzilla.mozilla.org/show_bug.cgi?id=1045552 https://bugzilla.mozilla.org/show_bug.cgi?id=964031

here another page where it was discussed with same result that there is a bug in FF still since beginning of ICC-v4 support with some (not all) correct ICC-profiles (last summary at the end from Royce Howland on Sun Sep 09, 2012 8:19 pm): https://www.naturescapes.net/forums/viewtopic.php?f=2&t=221943&p=2139338
