Hi Freda, technically, multiple servers are involved. When I go to the Sign In page from https://www.att.com/ the page is on https://signin.att.com/ .

Firefox recently rolled out "Total Cookie Protection" to more users. This limits how sites can use "third party" cookies, meaning cookies from different servers than the one you see in the address bar. If AT&T needs "cross-site" cookie sharing in order to work properly, then you will need to make exceptions. Here's how:

On each different AT&T server you notice in the address bar, turn off Enhanced Tracking Protection. To do that, click the shield icon to the left of the lock icon in the address bar. Then click the slider switch to turn off protection.

Any improvement?

More info in the following articles:

• Introducing Total Cookie Protection in Standard Mode
• Total Cookie Protection and website breakage FAQ

This suggestion did not resolve the problem. Now I'm getting the below message.

We want to keep your info safe We haven't noticed any activity in a while. We're redirecting you for your security.

Please help me fix this, as I don't want to continually move between browsers.

many thanks,

Freda

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
