Reporting weird bug. I had placed someone on ignore. When I went to a forum, he happened to be the only poster there. Instead of displaying no posts due to the ignore, it caused my brower to error out:
Redirection limit for this URL exceeded. Unable to load the requested page. This may be caused by cookies that are blocked.
After removing this guy from ignore, the forum displayed fine. My FF accepts all cookies and destroys them when the browser is closed.
