PNG images appear desaturated.
When I view web pages containing PNG images, the PNGs (as opposed to JPEG and GIF images) appear more desaturated than they should. This is a very recent problem, and it is unique to Firefox, as the same images look normal in other browsers.
I recently updated Firefox to version 3.6.15; however, I cannot be entirely sure whether this issue began immediately after the update, since it took me some time to notice it.

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.

Caveats: The new QCMS color management system introduced in Firefox 3.5 currently only supports ICC version 2 color profiles, not version 4.
