Agreed. For now, Orbot does this, and we don't need to expose it inside
of Orfox for now.

We must decide which functionality is required or just nice to have.
Screen size spoofing is complicated because mobile screens are radically
different and change quite a bit, and inherently you want the screen to
work with the display, else users will be annoyed. This may be an area
where we just can't match Tor Browser's anti-fingerprinting features.
Otherwise, Amogh and I will work through the Bug 1506 comments.
