Question I go into yahoo mail to check my mail and something strange happens. After I click mail in my yahoo main page, it loads and takes me to my inbox page. On the left I have my standard inbox, sent, trash, spam, etc... and the inbox is the default screen with a list of emails. Since a few hours ago, I have had the TAB ot the top of firefox showing my active tab scrolling back and forth between "rico_reardon - Yahoo! Mail" and caro24lb@hotmail.com ... sent you a new message. - Mozilla Firefox I do not know this person well and they are in another country. Colombia. I have tried to clear cache, history, everything. Run windows defender, run kaspersky internet scan, closed and reopened Yahoo, log out and then back in, closed Firefox, shut down whole computer... Done everything, but everytime I go to Firefox, and then sign in to Yahoo Mail, this tab flashes back and forth between "rico_reardon - Yahoo! Mail: and "caro24lb@hotmail.com sent you a new message. - Mozilla Firefox." I have even shut down the computer, then logged in via my iphone to see if there was mail waiting in my yahoo account inbox on iphone. (same account) Please tell me exactly what I can do. After signing in on computer, then going to yahoo, then clicking the check mail icon, the green circle spins on top left tab in firefox, then it seeems to flicker many times while bringing up the page, then loads page, but the tab heading scrolls back and forth between the two things I tell you it says????? PLEASE HELP... rico_reardon@yahoo.com
