It's not globally set to your system's active color profile (ICC profile) by default, so your carefully dialed in color calibration is useless... you HACK it! Did you know that?
Don't you long for a color calibrated FF?[/i]
The magic hack:
Get your colors right in Firefox - enable ICC profiles!
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.
