Comment (by gk):

 Replying to [ticket:18097 arthuredelstein]:
 > In #13313, we introduced a Tor Browser pref, "font.system.whitelist",
 which accepts a list of fonts and excludes all others from the browser. We
 introduced a separate whitelist for OS X, Windows, and Linux.

 I stumbled over that one while preparing the changelog for 5.5 and after
 some digging it occurred to me that we dropped the `font.system.whitelist`
 approach for Linux by shipping all the bundles ourselves and use the
 `fonts.conf` mechanism. We might want to clarify that point more in the
 description.
