[bill-auger]

when trying to log into firefox sync - i can get to the sync pane in 
preferences but when i press the "sign in" button the browser tries to load 
"about:accounts?action=signin&entrypoint=preferences" abd shows a spinner that 
never completes - in the console i see the followning errors:
