I am getting the below message when trying to log into the EFTPS site. I have never had this issue before.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.eftps.gov because this website requires a secure connection.

What can you do about it?

www.eftps.gov has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Firefox blocks a web site citing out of date reference. I go to certificate manager to overide, but am told firefox determines site to be legitimate and therefore will not overide. I am totally frustrated and confused!

Https:// does not show. every time I get an update something changes when I start. Unable to pull up Rumble, Beforeitsnews, amg-news. This started sometime yesterday. Please advise. To be clear, Windows 11 was installed, it started issues then. Just so you know, I am totally clueless with setting up computers
