Firefox 3.5 will, by default, use color profiles if they are included in images on a page to transform from the image's original color space into the output device's color space.  (A so-called "tagged" image.)  This support was also available in Firefox 3, but we've made the color correction process about 5x faster in Firefox 3.5 so we were able to enable it without the associated performance penalties.
