I can't connect to Facebook, it doesn't even register the site, and I can't even ping it in CMD?

I can't connect to Facebook. I could this morning, but suddenly I can't anymore. It tries to load, and then says "The connection has timed out".

I also can't connect with Internet Explorer. However, I can connect with Firefox, or IE from other computer (Other computer also has other internet provider).

I can connect to any other site on the web, like I am now on Mozzila support.

When I go to run, CMD, and type "ping www.facebook.com" it also says "Request timed out", and 4 packets lost. When I ping it, I get "star.c10r.facebook.com [31.13.64.65]". When I search for that IP i get "Facebook Ireland Ltd".

When I do same ping on my other computer (and other internet provider) he pings "star.c10r.facebook.com [179.60.192.3]" and pings correctly. From that other computer I also can't ping first IP (31.13...), but from first computer (on which I can't go to Facebook site) I can ping second ping (179...) correctly, but I need to type it in manually. When I just type "ping www.facebook.com" it gives me that first IP that doesn't work (31...).

Why does it happen, and why do I get different IP's when I type "ping www.facebook.com"?

Any idea how to fix it?

If you can't get it with cmd ping either, it's not a firefox problem.

Do you use a proxy?

Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}


Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select Network. Look for Configure How Firefox Connects and press the Settings button. Check the settings.


Contact your ISP and have them check your service.

Update: the problem seems to have repaired itself. I restarted the computer, but nothing happened. It was late so I turned off computer and went to bed. In the morning everything was working again - I could access Facebook without any problem.
