New submission from Akkana Peck :
http.cookiejar.MozillaCookieJar only reads from cookies.txt, a format that
Mozilla hasn't used in over a decade. It should read the file mozilla actually

fewest code changes, is:
from gi import pygtkcompat
pygtkcompat.enable()
pygtkcompat.enable_gtk(version='3.0')
I don't know if pygtkcompat is going to be supported
