epiphany developers have still got a very limited extension interface, because of the lack of pyxpcom support in distros. They have said that once it's supported, they'll implement the rest of the interface will.

Already pyxpcom has been added to ubuntu by a debian dev, so ought to be in debian too. I'm pretty sure its in fedora as well.

It's no extra trouble to enable, just change one line in xulrunner's mozconfig and add python/xpcom on the end.

ac_add_options --enable-extensions=default,cookie,permissions,python/xpcom

Compiles and works fine here, epiphany and firefox still work fine. Shouldnt be neccessary to add python as a dep, as its an optional thing -- and those using epiphany will already have python.
