Firefox and wide gamut - images sometimes oversaturated

Recently I've moved to a wide gamut monitor and noticed that while viewing photos using Firefox on POTN many of them look very over-saturated and overly contrasty. My monitor is calibrated with Native (full) gamut. Most of the images (but not all) that have this problem seem to be hosted on Photobucket.

If I save the same image onto my computer and view it with Photoshop it looks fine.

It looks like Firefox (I'm using 13.0.1) has a problem handling images that don't have an embedded ICC profile. However, it turns out that this is a known "problem" and someone has made an add-on that fixes the behavior. The add-on is called "Color Management" and lets you enable color management for ALL images instead of the default which is only images with embedded ICC profiles. After installing it I'm now able to view all images on POTN as the poster intended them to be seen If you keep your calibrated system as wide gamut and you use Firefox I recommend trying this out. Here's a link to the add-on: https://addons.mozilla​.org …x/addon/color-management/

Here is a screen capture of the "Options" screen for the Color Management add-on:

More, for those who are interested: why does my JPEG image appears as different in other image viewers ?

Thanks for the contribution Frank.

Moving to a wide gamut monitor calibrated in Native (full) gamut has a few challenges, but so far most are easy to deal with:

1. Windows desktop isn't color managed, but this is dealt with easily by using an aRGB image

2. Windows Media Player and Media Center aren't color managed. Quicktime is, but it's not a great program since you can't set it to always be on top of open windows. A better solution is to download Media Player Classic Home Cinema from Sourceforge and turn color management on. Works great.

3. As mentioned in my first post, Firefox isn't fully color managed "out of the box" and can't deal with untagged images. To turn on full color management you either have to change settings manually or use the "Color Management" add-on.

4. Avoid using IE9 since its approach to color management is half baked giving poor results on a wide gamut monitor.


Microsoft Office is supposed to be color managed, but so far I'm not happy with the results. When I paste an sRGB or aRGB image with ICC profiles intact into a Word document they look identical but for both the colors are off (too red when compared to Photoshop). On the other hand Windows Picture Viewer displays images identical to PS.
