Hello! I clear cookies and cache many times during the day when I am signed in to Firefox because I keep important data on Firefox. This did not help.

I tried logging again, and it just keeps buffering and buffering. I can use Chrome, but I don't like the safety of Chrome and I've come to rely on Firefox for that added protection. It's making me nuts trying to figure out why this happened approximately 4 weeks ago. I've never had a problem signing into this site with Firefox.

Thank you for your time! Karen

Is there a way to speak to a human being?

Have you tried Troubleshoot(Safe) Mode?

Hello! I have cleared cookies and cache several times. I opened the website in Troubleshoot (safe) Mode and I still cannot open the website that I am having trouble opening. I attached a screen shot of the Troubleshoot information, I have absolutely no idea what to do with it. Thank you so much! Karen

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

If the problem goes away with the computer in Safe Mode, the problem is with one of the other programs on the system.

As a test, disable your protection programs.

Hi Fred! The site did work in safe mode. So now I will disable AVG and firewall and see how I make out. I will keep you informed. Thank you soooo much for your patience and help. You are a God send! God bless! Karen

Hi Fred! Turning off the AVG and firewall worked!!! Does that mean there is a problem with AVG? Is there something I need to do on that? Thanks again! Karen

You should contact AVG support. Good luck.

Hi Fred! I contacted Apple because I am still having the problem even with AVG disable and firewall disabled. They had me open a test account and I was able to get into all websites without any problem. Since I am only have this problem with Firefox and computer safety is off; it seems that my problem is with Firefox. I can open the website in safe mode or I can use the test account, but it seems stupid to have to go through those steps to access a locked website. Do you have any other thoughts? What would happen if I delete Firefox and reload it to my computer? Thanks for your time and help!

Reinstalling Firefox would only help if there was a problem with the program files.

Did you mean there is no problem with the computer in Safe Mode?

If the problem goes away with the computer in Safe Mode, the problem is with one of the other programs on the system.

Hi Fred -Yes, the computer worked fine in safe mode and when I signed in with a test account. How can I find out which program is causing the problem? Thank you!

The only way is to disable each program one at a time between reboots.
