 On my system (Windows XP SP3) TBB 2.2.24-1 alpha does not search for all
 installed plugins as TBB did before resolution of bug 2218
 https://trac.torproject.org/projects/tor/ticket/2118. TBB 2.2.24-1 alpha
 has the appropriate user_pref setting in prefs.js setting:
 user_pref("extensions.enabledScopes", 5);.

 On my system the only system wide plugin found by TBB 2.2.24-1 alpha is
 "Foxit Reader Plugin for Mozilla 2.0.0.1102". When testing portable
 Firefox 4.0 http://portableapps.com/apps/internet/firefox_portable and
 installed Firefox 4.0 all the system wide plugins are found, see this
 screen shot: http://i55.tinypic.com/33z2u7c.jpg

 So it seems user_pref("extensions.enabledScopes", 5); is working as
 expected, to a point. I tried other integers to prevent TBB 2.2.24-1 alpha
 from finding the Foxit plugin, i.e., -1 and 100, but they were not
 successful (I realize neither of those integers are options for
 extensions.enabledScopes). As per the bug report 2118
 https://trac.torproject.org/projects/tor/ticket/2118 I looked for the file
 "nsExtensionManager.js" but it does not seem to be used for Firefox 4.
