Firefox 3.5 – Disable GFX Color Management
Firefox 3.5 introduced a new feature GFX Color Management. Unfortunately, it doesn’t seem to work right.
Here is how to disable it
Type in “about:config” in the addressbar and click the button to gain access to the configuration
Type in “gfx.color_management.mode” and hit enter.
The value of “gfx.color_management.mode” should currently be 2, double-click the line and change the value to 0 to disable the GFX Color Management.
Restart Firefox
