Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Only got to Step 3- there is no CHANGE button,only ADD (I only have one email account).

Start in Safe Mode didn't allow me to log in to the Frontier account.
