 > When RFP is on, http header is spoofed according to a 2-tuple (windows
 on pc, and android on mobile). Entry in javascript navigator object is
 spoofed according to the 4-tuple described in the bugzilla ticket above
 (android, linux, mac, windows).

 it makes a difference since there were plenty already)
 At least it's somewhat ok since with JS fonts leak OS info, I'm satisfied
 for now with this work but I wish so hard that the great folks here
 wouldn't fall for such cheap arguments ("muuh changing UA will break this
 site that can't even be accessed anonymously!").
