Actually Firefox has had some "notion of color management" since at least 
version 3.5 (It might have been a little earlier than 3.5).  This is limited 
to monitors and the internal CMM is flawed and lacks support for ICC V4 profiles 
and profiles that use a LUT (unlike when Firefox was using LCMS).

There are more and more open source apps that are CM aware although most of 
these are enharently graphical in nature.  So we are seeing things like 
Blender (3D modeling program for animation and gaming) developement (V2.5) 
with some CM support.  I wouldn't try to print a profiling target from Blender 
since I don't think it is a good fit for this purpose but there are many other 
open source apps that at the very least have some CM hooks/awareness ranging 
from web browsers and PDF readers to high end graphics software such as GIMP, 
Scribus and Blender.

On the other hand if the print UI's "target printing mode", and perhaps some 
other "high end" CM, functionality required the calling app to ask for this to 
be visible to the user I think that we should be able to get most of the apps 
that are of interest for printing targets or doing app side CM (IE. GIMP, 
Kate, InkScape, CinePaint and so on) to add a call to turn these UI features 
on since it likely involves adding or modifying a single line of code if 
correctly designed.   But this implies that we can get both a working print UI 
and app(s) that inable the advanced CM features part of the UI at the same 
time to have a working solution.  This may be the difficult part since we don't 
have dirrect control over any of this stuff.
