Sign In button jumps left when Facebook button arrives!
In my case [FireFox 33.1.1 on Win 7 64bit] the "Sign In" button jumps left when the slothful Facebook button finally appears. The timing places the Facebook button under my mouse pointer at exactly the same time as perform a mouse click -- hugely frustrating!
I suggest you move the Facebook button to a position under or above the Sign In button.
