 Replying to [comment:11 gk]:
 > What about `bug_21396`
 (https://gitweb.torproject.org/user/gk/torbutton.git/commit/?h=bug_21396&id=3a285294fe1db84b140db456900cdbf9a62bab0c)
 in my public Torbutton repo?

 The patch looks okay. Kathy and I tested it with browserleaks.com but not
 with the Session Manager add-on. Just a few small things that you may want
 to fix inside the `shouldLoad()` function:
 1. It is inconsistent to not prefix `uriFingerprinting` with `this.` (but
 the code seems to work).
 2. It might be better to check `this.uriFingerprinting` first since the
 `schemeIs()` calls must take longer to execute than checking a Boolean JS
 variable.
 3. Adding braces wouldn't hurt.
