Nice. Some feedback: The "first run" page doesn't tell me clearly that anything has been installed or has started working. This kind of information should be really clear and prominent, the largest thing on the page. Instead it's not even there at all, as far as I can see.

Edit: Please don't reply and say "you can check if it's working by blah blah blah." That is missing the point. My point is that EFF should fix the extension to make this communication clear for ALL users.
