I have a Toshiba laptop, maybe 4 months old, running firefox on windows 7.I just booted up and I get the message; Firefox is having trouble recovering your windows and tabs with 2 boxes to check: restore or start new session, neither of which helps. When I click on the icon for firefox, I get Yahoo to come on for about 2 seconds and then it's gone. This happens no matter which box I check. What can I do to get back to the internet?
