Firefox cannot open this Page
Please see attached screenshot. I have been logging onto my Online Banking with Nat West and when I log out I am now getting the message Firefox cannot open this Page. I should see the Nat West page again straight away showing I have logged out of my Online Banking. The message refers to a security issue that a website has embedded onto the Nat West website.
When I use Safari the message does not appear which indicates to me it is a Firefox issue.
I am not certain what I should do to resolve this issue is this a Firefox issue or Nat West issue or a problem with my Mac computer.
Please can you advise me what I should do next to resolve the issue.
Thank you
