Different cache directories for each application would not be much of a step
forward. Apps can already get this by setting up their own profile directory
(indeed, that's what they do). Having apps be able to share a single cache (per
user) is a major usability win. Further discussion of this probably belongs in bug 135061.
Prefs... IMO, the most desirable situation from a usability standpoint would be
to have Gecko prefs shared. Apps that don't want that can set up their own
profile directories and share nothing with other apps.
