Hello,

Have you run any anti-virus software to make sure that there isn't any viruses on your computer? Also, do you have any content filters set up which might be blocking Facebook by accident? Do you have any cookie blockers which might prevent you from accessing facebook? Or are any cookie blocked in Firefox's settings?? Is java script enabled? (Check by going to about:config, type in javascript.enabled, and make sure that it is set to "true") If none of these help, when did this problem start to occur?

Thanks for your time, and for you to answer any of these questions!

problem solved - thank you guys - I was on Facebook when they had a shut down - must have locked up my system - did a systematic shut down of everything - I forget the modem the first time - bought everything back up one at a time and in order and then problem solved - thanks for you help

Yup, this was a Facebook mistake, just like you said.
