How to read Mozrepl Javascript result into a Python Variable?

[goldtech]

Hi,

With Mozrepl addon in Firefox and Python I do:

and I get an alert box with the URL of the active tab.

But how do I read that URL into a python variable? Something like tn.write(r';var zz = window.content.location.href'+ "\n") but that doesn't get it into python.

I would be grateful for help. Thanks.
