What gives? "The browser you're using is not allowing you to sign in to Excite."
I'm using Firefox 3.5.15 to access my email account at excite.com, as usual over many years. I have not changed any security settings or installed any new security software recently. My clock is set correctly on my Windows 7 system. There's plenty of space on my hard drive. Suddenly, I can't get into my Excite email account via Firefox, only IE8 (which sucks). Why?
