Not sure if anyone else is getting this, but today I tried to refresh the page and it locked up. So I used task manager to force close firefox so when I reopened it, it'd pop right back up. When I did...Is it me?
Certificate error, the cert for MFG most likely expired or doesn't exist. As yami said, you can avoid that message by being insecure about yourself or your MFG browsing.
certain websites' certificates and more importantly, certain certificte formats expired this year. until teh sites update their certificates, try changin the web browser, adding ac ertificate exception or disabling yoru antivirus, whatever works.
