This has become a very frustrating situation. I am facing a couple problems (that may be related) but I will focus on one here. My browser will randomly redirect me to the homepage of certain sites at random when I attempt to explore within the site. It has happened to different sites at different times (espn.com, macys.com, etc.). I recently cleared my cache and cookies and the problem persists. I have to close and reopen Firefox constantly. This cures it for a bit then it starts again. Example: Right now, when I go to the link scores.espn.go.com/ncb/scoreboard, I was redirected to ESPN's main page. But now, as I type this, my other problem has emerged. When I go to that link, I am redirected to a 404 Yahoo Page Not Found (http://us.yhs4.search.yahoo.com/yhs/errorhandler?hspart=visicom&hsimp=yhse-visicom&type=manycam__mystart_ad__1_0_1_108__yhse__antiphishing_dn_4909__rp&q=scores.espn.go.comncbscoreboard). This Yahoo 404 page has popped up numerous times when attempting to access various sites. I have to close Firefox and reopen it to eliminate the problem for a short time. Then it will happen again with another site. What is going on? This is driving me crazy.
