I have been using Firefox as my primary browser in Windows and Linux Mint for many years, and I have always found it to work when other browsers would not. Recently (last few months) functions in Ancestry.com stopped working. I thought that the problems were within the Ancestry system, and getting help within Ancestry was very difficult. I finally got a help chat session a short time ago and learned that everything in Ancestry should work using the Chrome browser. Very reluctantly, I loaded the Chrome browser on one of my Windows 11 computers, and suddenly all of the functions within Ancestry worked properly. I sincerely hope that FIrefox will soon resume being fully functional with Ancestry.com.
