Comment (by legind):

 Note that in the transition to the WebExtensions version of HTTPS
 Everywhere, we will no longer have access to browser prefs.  See:
 https://wiki.mozilla.org/WebExtensions/FAQ#Will_I_have_access_to_about:config_or_the_preferences.3F

 Because of this we won't be able to tell from prefs whether mixed content
 blocking is enabled or not, and setting the above-mentioned pref will be
 ineffective.

 One possibility is setting a localStorage variable
 ''enable_mixed_rulesets'' and setting that to the desired value within the
 HTTPS Everywhere extension scope at browser startup.
