FIREFOX இல் YOU TUBE, FACEBOOK ஓபன் ஆகவில்லை என்ன காரணம்
Unable to connect
Firefox can't establish a connection to the server at www.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.
