Does that mean you cannot get to the site or you're having issues logging in? Provide screenshot(s) of the issue and block any personal info.

You can also try the below steps. Firefox in Safe Mode - https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

I can get onto the site but if I try to move on to the online banking part nothing happens. I have cleared history , cookies and cache

Can you post a screenshot showing what happens when you try that site? What happened in Safe Mode?

Thanks for your help. Problem solved!

What was fix? Also, mark this issue resolved. ;-))

I opened Firefox in Troubleshoot mode and followed the advice there - I can't remember precisely because I am not at all technical so sorry if this is not totally helpful

Ok, mark it as resolved and have a good day. ;-)
