Public bug reported:

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.
