Comment(by mikeperry):

 Hrmm.. Anything I do here seems like it is going to have to be in C++, or
 in a new JS XPCOM component. JS would obviously be simpler, make it easier
 to inform the user, and be free of cross-platform woes, but more of the
 browser will have loaded by that point.

 As for the actual test, I can think of a few options:

 1. TOR_SOCKS_PORT env var check
 2. Check that the profile directory is set as expected
 3. Check that certain about:config prefs are as expected

 We want this by Monday?
