Comment (by mcs):

 There is a lot of information in this ticket but I do not understand what
 is broken.

 If you create a profile that looks exactly like the one that we bundle
 with Tor Browser, everything should work exactly like it does with the
 bundled profile (profile.default).  We rely on the default preferences
 that we build into the browser as well as the ones that are included in
 the profile via extension-overrides.js.

 I tried that by doing the following with Tor Browser 4.0.3 and everything
 appeared to work fine:
 1) Ran firefox -p, created a new profile, did not start the browser.
 2) Copied the extensions and preferences directories from profile.default
 to the new profile.
 3) Started Tor Browser using the new profile.

 And a request:  please respond when Tor engineers ask for clarification
