color management broken in firefox

[Per Ångström]

Binary package hint: firefox

Firefox, using standard settings, renders a jpeg containing an embedded sRGB color profile with different colors than a jpeg lacking an embedded profile. Firefox's rendering of the jpeg containing a color profile is also different from that of other applications.

How to reproduce:
0) Make sure you have the default Firefox color-management settings:
gfx.color_management.display_profile: (none)
gfx.color_management.mode: 2
gfx.color_management.rendering_intent: 0

1) Load a jpeg having an embedded sRGB color profile in Firefox.
2) Load a profile-stripped version of the same jpeg in another Firefox tab.
3) Compare the images.

Expected result: The two images should look exactly the same.
Actual result: The two images have different colors.

You can also load the images in Gimp and compare to Firefox's rendering.

You can achieve identical rendering of profiled and non-profiled images by turning off color management completely in Firefox.

In all fairness, it is only on one of my three machines I can see this problem.

I managed to correct the color display by assigning a value to gfx.color_management.display_profile: "/usr/share/ImageMagick-6.6.2/config/sRGB.icm".

[Per Ångström (autark)]

I found the following page: http://www.gballard.net/psd/go_live_page_profile/embeddedJPEGprofiles.html
Experimenting with the different images, I find that Firefox seems to be using "ADOBE RGB (1998) 2.2 gamma" as default, unless I assign a value to gfx.color_management.display_profile.

I can reproduce this both in Firefox 3.6.11 (Ubuntu repositories) and in 4.0b7pre (Mozilla-built).

This also happens on Natty (20110219) on firefox 4.0b11 (Ubuntu built).

Using the instructions posted on comment #5, the colors are reproduced correctly.

By the way, viewing the image I attached on comment #9 with firefox, the colors of the images inside the displayed web page are shown correctly and the others are shown incorrectly, somehow reversing the previous effect.

Also affects Firefox 4.0 with Ubuntu 11.04

Hi,

I'm also affected by this bug (Firefox 4.0 on Ubuntu 11.04)

[Lukáš Chmela (lukaschmela)]

Affected too. Firefox version 5.0+build1+nobinonly-0ubuntu0.11.04.2 from natty-updates, using Ubuntu 11.04

Hi,
I have the same problem with Ubuntu 14.04 64 bits (firefox 38.0+build3-0ubuntu0.14.04.1).
Does that mean that this big has existed since 2010 and is still unfixed 4 years later ? Sounds weird...
