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? I tried disabling all my security software, including Zone Alarm, Avira, Iobit, etc, and restarting the computer and then the browser. All my settings allow cookies & Javascript. I put Excite under "ALLOW" for every exception in the Firefox settings. I verified that my Excite cookies were still there, then tried again after deleting them all. No effect. Just the troubleshooting information, below. Any ideas???
