Facebook is not opening in any browser?

i scan my pc several times, i reinstall my browsers then also facebook is not opening:no: Help Me, how to solve this problem?

Well, have you tried to install anything prior to when facebook was opening fine? Can you try to uninstall all the web browsers from your computer and then install it again and see if it is able to open Facebook now. If this still doesnt work, then turn off your firewall or antivirus software which might be blocking access to facebook website.
