On Ubuntu 10.10 and 11.04 64bit photos render very poorly when the setting gfx.color_management.mode is set to 1 or 2.
When set to 0, everything appears fine.

Reproducible: Always

Steps to Reproduce:
1.Clean installation of Ubuntu 64bit
2.Look at pictures.
3.Set gfx.color_management.mode to 0 and look at pictures again.

Actual Results:  
explained already

Expected Results:  
...

In Windows 7 the setting is set to 2 and pictures appear just fine.
I use a toshiba a505-s6960. Maybe it's an issue with the intel graphics card and open gl.

It sounds like you have a local problem with your color profile and I doubt the best solution to that is to turn off color profiling in Firefox on each and every Linux computer in the whole world.

Have you compared the result by looking at the images in another color-managed program?

Any links to images that you think render poorly?

^ That's a side-by-side comparison. The numbers represent the picture rendered when gfx.color_management.mode was set to that value. All sites are effected however.
I used gimp to view the program the picture and turned color management on and off. The picture rendered just fine.
Rendering intent in firefox and gimp were both set to perceptual.

Firefox 7.0.1 in Ubuntu 11.10 64bit manages a bit better, but color is a bit off.

I experience problems with color management too. Colors of many images are way of. Purple and green. I reported this bug before, and i think it was fixed, but now with the latest 9.01 release it happens again (regression). The problem in my case is also to disable color management. Maybe a solution would be to include color management in the menu of firefox, instead of the, for many, cryptic about:config. I will attach an example of facebook with colors way off. Please do something about it. Many people do not invest time in reporting issues, they just change browser and all other browsers work just fine.

Using Ubuntu 11.04 32bit Firefox 9.01 ATI radeon graphics card.

Looks like color management on Linux is hurting us more then helping. I agree that we should consider turning it off until we can investigate the regression.

Jeff?

I'm sorry, i wanted to say 

The solution in my case is also to disable color management by setting it to 0 in about:config

With firefox 14.X, the problem is resolved.

On Firefox 70.0.1 this is still present.

Colors are incorrectly represented - when compared to Chrome or GIMP.

After disabling color management, I got feeling that it rendered images correctly but now I am comparing Invision designs and those look totally different. This is very annoying bug and without workaround I would need stop using Firefox at all :( after more than 10 years.

Bugbug thinks this bug is a regression, but please revert this change in case of error.

Would like to edit my previous post but dont see way. Here is my update:

After updating about:config gfx.color_management.mode to 0 images got proper colors in Chrome and in Firefox.

But, for some reason Invision designs still look noticeably different. I was trying to dig into that, but looks like in Invision designs there might be composed with multiple semi-transparent color layers - so final color is mix of semi transparent color and background under.
This probably leads to different calculation of final color on different browser engines.

Still looks like calculation on Firefox is less correct, than on chrome. But probably this is mainly issue of designer who provided such design, without directly defined color, but using some weird transparency trick to mix color.
