 Replying to [comment:14 rustybird]:

 > Hmm, now that you mention it... If this race hypothetically affects real
 websites (i.e. not just `about:blank` and empty `data:` pages),

 It should not: NoScript defers all the HTTP(S) traffic until its policy is
 configured and ready to be enforced.
 about:blank, data: and file: URLs are those which might suffer of this
 problem, because NoScript has no means to prevent them from loading before
 it's initialized.
