Today, after updating the browser. I can't sign in to Ancestry.com

I don't know why, it is NOT Ancestry, as I can sign in to it on other browsers. I get this error message below.

Access Denied Error 21 What happened? This request was blocked by security rules. Your IP: 73.94.12.65 Incident ID: 6eae587fcef92d46

I have no idea what security rules, but I am working on a genealogy project and have never had a problem signing into Ancestry in multiple tabs before today. How do I fix this? Besides getting rid of Firefox, I mean. I have the same security extensions on this browser as I use on Vivaldi, Brave and Chrome - I avoid Chrome, but use Vivaldi and Brave regularly, along with Firefox.

It could be the data for the website was corrupted. Removing them also removed the problem.
