I have always used Firefox to log in to my Tesco Bank account, but for the past few days I am getting this message that Access is denied on this server, yet I can log in OK from other browsers. I am based in the UK. I use a laptop, Windows 10, have done disk clean up, removed cookies & cache - all the usual stuff, but still get the same message. All other websites are working fine, any ideas why I am not allowed to go into my Tesco Bank account when using Firefox? Any help much appreciated.
