Login on Firefox WONT WORK!

[Aristeas]

Hi, having no success fixing a login problem on Firefox.

Login works fine on IE

On Firefox I get as far as the password and then get a repeating 'Security Check' page that won't load fully before reloading. Can't get anywhere with it. 

I have deleted all history, cookies, etc several times.  No difference.

First time this happened I got as far as getting a security code but nothing made a difference.. 

Help!

Have you updated to the latest version of FireFox?  https://www.mozilla.org/en-US/firefox/download/thanks/
