Just for the h* of it, I thought I'd Google the FF message you quoted. Google returned roughly 6,000 exact matches. I'll link to the first one, which I assume is OK, since it's Mozilla Support....
how to avoid, "firefox prevented this page from automatically redirecting to another page."
Firefox/Firefox > Preferences > Advanced > General : Accessibility : [ ] "Warn me when web sites try to redirect or reload the page"
The setting in "Firefox > Preferences > Advanced > General" is meant as an accessibility feature, as you can see by the label of that section, so that people with disabilities or people who use screen readers do not get confused and is not meant as a safety protection to stop redirecting.
