Back near start of 2024, an update to Firefox resulted in "Primary Password" being dropped when ever "Clear Recent History" is done. Requiring you to re-enter your "Primary Password". Prior to 2024, a "Clear Recent History" could be done and your "Primary Password" was not dropped (not effected). Initially, I thought it was a code problem which would get fixed with next update of Firefox. However, the problem has remained. I have not been able to find a way to tell Firefox thru preferences to or config to not clear "Primary Password".
