Can anyone tell me how to find my favorites. I finally "upgraded" to IE8 from IE6. It will only import some old, old favorites. I have had the same problem with Chrome. I have searched and scoured my system for a bookmark or favorites file that has the IE6 info, but it ain't there! The IE6 version was from Verizon, optimized for MSN or some such version. I have to use IE6 as a browser if I need to go to one of these favorite sites. The IE6 has NO export function. Windows XP SP3 otherwise running just fine. Thank You.
