When on a website, filling out an application,etc and they ask me to provide an email address, even though I type it in the box provided it doesn't register. This has started to happen within the last 2-3 weeks and it prevents me from filling out forms and applications that ask for my email address or even an alternate email address. The box will simply light up and keep telling me to provide an email address and therefore won't allow me to finish the application and/or form. If I go to Safari, I can successfully accomplish the task. So I know it's something in Firefox that's causing this to happen. Please help.
