How to enable color management in Firefox 3

Before enabling color management

After enabling color management

Color management allows images and colors to be displayed consistently across a variety of devices. Mozilla recognizes embedded ICC profiles in image files and uses a local color profile to perform the color adjustments. This preference determines if Mozilla should make these adjustments. It's turned off by default.

Why isn't this value true by default? Well, according to Mozilla, you'll see a 10-15% performance hit using this setting, but if you've got a reasonably fast machine, it'll be worth the better-looking photos.

Here's how to turn it on.

Method 1 Manually edit the colour management setting

1. Type about:config in Firefox 3's address bar and press Enter.

2. A warning dialog box appears - click "I will be careful, I promise!"

You will see a long list of configuration.

3. In the Filter field, type gfx.
you're left with 3 config:

gfx.color_management.display_profile default string
gfx.color_management.enabled default boolean false
gfx.use_text_smoothing_setting default boolean false




4. Double click on the second line -

gfx.color_management.enabled default boolean false

and the value will change to true -

gfx.color_management.enabled default boolean true

5.Quit and relaunch Firefox 3. And your firefox is now colour managed.


Method 2 Install the Color Management add-on

There are two ways to turn on color profile support in Firefox 3. The easiest is to install the Color Management add-on . After you install the add-on and restart Firefox 3, color profile support is enabled, and you can specify a custom color profile by going to the Tools menu, selecting “Add-ons”, and clicking the Color Management add-on “Preferences” button. If you do not specify a color profile, the system default profile will be used, which should be OK for most people.
