Please see my original question above. Since I switched from IE to Firefox, I cannot even view medical claims on Aetna. Even YOUR help site, had an expired certificate notice come up and I had to click thru the 'override' tabs to continue. I am getting 'Security Alerts' for expired security certificates on almost every single web site I go to. I just keep clicking "yes" when asked do you want to continue. This is horrible. I tried to use a page I found that tells me to go to Tools, then Options, then Web Features to "Allow sites", but there is NO "web feature" choice to click.
