Previous laptop had firefox 3.6 loaded and I had no issues getting to dishmail.net or comcast.net to retrieve my e-mail. Firefox 3.6.11 (or .12) blocks me getting into those sites "for security reasons" and won't let me get to sign-in to get to my e-mail. I can access the sites and my e-mail through Internet Explorer just fine, but would rather not have to switch back and forth. How can I get rid of this nuisance block?
