The is a problem with Firefox when the date on the board is more than 30 days in the past. We set the date on the image when we upload it but unless the board has a way through DHCP or NTP to update the time it will drift. If you update the time on the board using sudo date -s "YYYY/MM/DD hh:mm:ss" this will allow you to use Firefox.
