 Please warn with a notification bar if xpinstall.signatures.required is
 set to false.

 This setting was recommended by the blog for users affected by #30388 .
 Such users are somewhat likely to forget to toggle it back to true, which
 could be a potential attack vector.

 Quoted from comment 43 there:

 > > Since the blog asked people to "Please remember to" re-enable
 security, and that's the kind of thing which is the bane of security when
 it comes to ordinary users, can a subsequent release please force this
 back to 'false' and alert the user if the flip is made?
 > >
 > > It's better to have people need to toggle it again than to leave
 people unintentionally unguarded. I realize both options are sub-optimal,
 but "fail safe" is better than "fail dangerous". Without such a change,
 it's very likely that some users will go on forever set to not validate
 addons - the typical user pattern is "fix it and forget it".

 prefs. We could think about showing a notification bar, though, reminding
 the users of that problem and allow them to flip the pref back easily that
 way.
