Upgrade to FF 20.0.1 on Win/XP broke online access to yahoo mail. At logon to yahoo mail I get stuck at us-mg6.mail.yahoo.com. * Yahoo mail worked just fine before the upgrade (at FF 20.0.0) * Yahoo mail continues to work just fine using IE8. yes the cache was cleared out ... yes i tried disabling all extensions and add-ons ... yes i have this problem on two separate laptops. Thx for any help.
