Comment (by cypherpunks):

 Can you ask Mozilla to change exposing `resource://` URIs opt-in for each
 extension via manifests (because some non-TBB extensions need it) and
 eliminate `resource://` exposure in Firefox core? This is important
 upstream too. It is actually one of the most critical holes in Firefox
 (now with `Components` deprecated in Web). TBB's OS mangling is only half-
 baked with this problem unresolved. So each anonymity
 set is quite a bit smaller than imagined.

 https://bugzilla.mozilla.org/show_bug.cgi?id=863246 is inactive now. It
 seems '''we need more attention from Mozilla'''.
