Hello daisy,

In order to enable and properly configure Firefox color management,

follow the steps below.

Enable it on the Firefox advanced configuration

Type in about:config on your Firefox address bar.

Use the filter field to search for color_management.

Update the following fields:

gfx.color_management.mode

Set to 1 to enable color management for all rendered graphics.

The default value of 2 enables color management only for tagged images, so all page elements and untagged images are rendered in the monitor full color gamut, leading to oversaturated colors.

gfx.color_management.enablev4

Set to true to enable ICC v4 profile support.

There's no need to specify the monitor ICC profile manually as it's read automatically from the operating system.

Restart Firefox.

Thank you!!

This is exactly what I did and did NOT solve the problem after restarting. My images looks oversaturated even on Mode 1 and true ICC V4 profile. Any other suggestions? Thanks Daisy

Hi daisy.gilardini, glad to see you on Mozilla Support Forum.

This can be caused by a problem with the color profile for your display monitor or color profiles embedded in images.

You can disable color management to test that.

You can set the pref gfx.color_management.mode to 0 on the about:config page to disable Color Management.

You need to close and restart Firefox to make the change effective.

If it doesn't solved your problem, then feel free to ask in Reply Section. Thanks for raising your question in Mozilla Support Forum.

Thanks for your reply. I did disable and re-enabled color management exit each time Firefox. But no changes in color. All my images have a sRGB color profile. Any other suggestions? All the other browser show my picture color correctly. I am a professional photographer and use an EIZO monitor so I am picky with color calibration. It is now years that this problem is persisting. I might stop using Firefox if I don't find a solution. Thanks Daisy

I used 'Colorful tabs' but had an issue with my PC & they deleted that after saying that 'Colorful Tabs' couldn't be verified. How do I get setup with tabs that show-up as separate tabs & I assume set apart by color?

I need those immediately as I cannot easily tell one tab from another! Does a different add-on do a similar job? Naturally I need that information asap.
