Facebook test accounts using selenium - failing to

I am programmatically creating test accounts, and then immediately trying to log in w/ them using a selenium driven browser. Unfortunately, the browser is just redirected to the facebook homepage. I can briefly see what appears to be the correct url prior to the redirect flash by, so I have no reason to believe the browser isn't going where I intend it to.

That said, if create a fake account, and then just paste the login_url into a browser, things work fine. Anyone have any idea why that might be unique about using Selenium here? Is there anything I need to do to prepare the browser for https connections or anything?

All I'm doing is this: (using capybara and the Selenium web driver)

visit @fake_user.login_url

Visit Facebook home page before trying to visit login url:

visit "https://www.facebook.com"
visit @fake_user.login_url

I haven't checked the headers, but I guess Facebook sets some cookies that are needed to log in.
