I had a problem accessing my bank account online. I contacted them and they gave me a temporary password which meant I had to change it the next time I accessed my bank account. When I tried to do this I got the message "Firefox prevented this site redirecting you to another page" . When I clicked on the "allow" button, Firefox would still not allow the redirection no matter how many times I clicked on it. This is not good. In the end I accessed the site through Internet Explorer and was able to successfully change my password and use my bank account online. I should have been able to do this with Firefox which is my default browser. I am now having second thoughts. PS - I just tried to "automatically add" troubleshooting information to help and got the message that Firefox prevented support.mozilla.org from installing something on my computer ! ! !You could not make this up.
