Try enabling ICC version 4.
- Open a new tab in Firefox and go to
about:config
. - Type in
gfx.color_management.enablev4
into the search. - Double click on that string to enable it (set it to TRUE).
If that does not reproduce the results, try messing around with the gfx.color
settings in about:config
.
Also, open Firefox in Safe Mode (Firefox button -> Help -> Restart with Add-ons Disabled) to see what the default view is.
Finally, make sure that your client is using an up-to-date version of Firefox, since older versions presumably have different quirks and levels of colour profile support. Try testing on another machine to see what it displays.
