Bobby Holley has been refining Mozilla’s color management backend, working to improve performance and polish the feature so it’s ready for “prime time”. These efforts have clearly paid off, as color profile support has now been turned on by default for tagged images in the latest Firefox nightly builds. In this context, “tagged images” are any images displayed in the web browser that have an embedded ICC color profile — in other words, images that contain the information needed to do a specific and accurate color transformation. Bobby’s post goes into all the technical aspects of these changes in detail, and also discusses why color management hasn’t been enabled for everything at this time. Percy Cabello has also posted about these changes over at Mozilla Links.
