Since the last auto-update of my Firefox browser, emails that contain forwarding URL, those URL will not execute. For example, I get a daily trivia question. When I click on the link to answer the quiz, Firefox locks up. The same happens with a Facebook link. If I use a different browser (e.g., Opera), the links work fine. I've tried to notify Firefox, but getting a link for them is a bad joke. Has anyone else experienced this?
