I am no longer within range of a network that I was ''attempting'' to connect to as ''guest'' and now the guest registration page for the network overrides the url that was set for my home page in Firefox. (I never actually established a connection to the internet on that network because the guest username and password repeatedly failed.) The redirect executes whenever I type the URL, www.yahoo.com, into the address bar or when I follow a link from a search engine to that URL, or when I click the home button. How can I stop the redirect? I deleted all network locations that contained that network and cookies that contained the network name but that did not stop the page redirection. I do not believe this to be a virus or malicious network because it was at an research institute. I looked in prefs.js for any keywords from that network but I did not find anything obvious. Thank you for your help.
