As you probably know, not all software applications support ICC profiles. This often leads to confusion: You might for example be viewing an image in the Safari browser, which does support ICC profiles and therefore displays colors correctly, whilst a client of yours might be looking at that very same image in Internet Explorer and see something entirely different.
What about Firefox then, you might be asking? Well, the latest version of Firefox (3.x) actually does support ICC profiles, although not by default - you actually need to switch that option on first. How? You just open a new window and type “about:config” in the address bar. After hitting enter, the app will give you a warning, that changing advanced settings is only a good idea if you know what you are doing. Once you’ve confirmed, you’ll get a list of entries. Filter out the ones with the word “color” in them. At the bottom, you’ll find one called “gfx.color_management.enabled”. Simply double-click that line, and the setting in the “Value” column will change from “false” to “true”. Now quit and re-open the app. That’s it! Your Firefox now supports ICC profiles.
We’ve prepared two test images, that allow you to check whether your current browser
supports ICC profiles or not:


Do the photo’s colors look normal to you? Is the word “Red” in the second image actually red, the word “Blue” actually blue? If so, your browser currently supports ICC profiles. If not, you might want to switch to one that does.
