Reproducible: Always Steps to Reproduce: 1.Visit one of the pages above with FF3b5 Actual Results: Pngs with colors like ffff99, ccffff are darker than the colors themselves. Expected Results: PNG and background colors (both HTML and CSS) should be the same.
Do you have a color profile set? See http://kb.mozillazine.org/Gfx.color_management.display_profile for documentation.
With color profile works fine. (gfx.color_management.enabled;true) Shouldn't ColorProfile be supperted in Firefox as default (like it is in Safari - i've read -)?
Well it is not enabled by default, bug 418538 - Enable color management support by default. Which might make this a dupe of that bug.
Yes, it's a dupe.
