I have several email accts with yahoo mail, with usernames and passwords saved by FF. Lately when I select a username and pw and then hit the "sign in" button, nothing happens, the lower left screen shows "Done". If I navigate to another web page, and then clear history/cookies/etc, and then go back to yahoo mail, I can log in with no problems. FF is set to allow cookies for https://login.yahoo.com/config/login_verify2?.intl=us&.src=ym I can access yahoo mail using IE and Chrome, prefer using FF (not ready to upgrade to current version yet) I did two uninstall/reinstalls and a system restore to earlier this week, did not help
