@chrisy25

Try opening Facebook on IE or Opera or Safari. Is the site opening on these browsers ??

If your problem exits only on Firefox - Firefox cannot load websites but other programs can

If you problem exists on All browsers - No programs can load websites

Check and tell if its working.

Unable to connect

         Firefox can't establish a connection to the server at facebook.com.
    

 The site could be temporarily unavailable or too busy. Try again in a few
   moments.
 If you are unable to load any pages, check your computer's network
   connection.
 If your computer or network is protected by a firewall or proxy, make sure
   that Firefox is permitted to access the Web.

i tried clearing my cache and cookie, changed the DNS serve, checked no proxy, run my computer in safe mode , and nothing seem to work at this point i will try any thing

Cannot connect after upgrading Firefox

i have the latest firefox

go through the article mentioned in my previous post and perform the steps as suggested in the article

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

• Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

"Remove Cookies" from sites causing problems:

• Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

• Don't make any changes on the Safe mode start window.
• https://support.mozilla.com/kb/Safe+Mode

• https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes

Do a malware check with some malware scanning programs.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.
