+Subject: [PATCH 01/26] Block Components.interfaces from content
+
+This patch removes the ability of content script to access
+Components.interfaces.*.
+
+Components.interfaces is useful for fingerprinting the platform, OS, and
+Firebox version.
+
+It appears to have no other legitimate use. See also:
+https://bugzilla.mozilla.org/show_bug.cgi?id=429070
+https://trac.torproject.org/projects/tor/ticket/2874
+
+Note: We no longer block Components.lookupMethod, because we no longer rely on
+JS hooks for fingerprinting defenses.

-Subject: [PATCH 01/24] Block Components.interfaces,lookupMethod from content
-
-This patch removes the ability of content script to access
-Components.interfaces.* as well as call or access Components.lookupMethod.
-
-These two interfaces seem to be exposed to content script only to make our
-lives difficult. Components.lookupMethod can undo our JS hooks, and
-Components.interfaces is useful for fingerprinting the platform, OS, and
-Firebox version.
-
-They appear to have no other legitimate use. See also:

 This defense has been improved since that blog post to additionally randomize
 the order and concurrency of non-pipelined HTTP requests.
+
+This patch is also different from the 10.x ESR patch, as the pipelining
+code has changed. We may want to set network.http.pipelining.aggressive to get
+similar behavior...
+
+The good news is we now randomize SPDY request order as well as pipeline
+request order (though SPDY is still disabled by default in TBB).
