When I click on continue I'm seeing several messages logged to the console, including one which implicates the SmartBlock Facebook SDK shim. Apparently there are a few methods on the window.FB.AppEvent now which either overlooked before or may not have been there when the shim was written, including a logEvent method, which this page assumes will be there. Adding it seems to fix this. I'll write a patch ASAP.

The candidate patch here landed as part of bug 1752990, and the page seems to work fine now for me in the latest nightly.

I can confirm this is fixed, redirect to "Phone code" verification is done now with ETP - Strict.
