maybe you set up secure Browsing (Https) in Facebook, in account security
or your security tool is doing this
(firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

If this is your computer at work, then the System Administrator (your friendly, overprotective, paranoid, control freak IT department) has blocked that site and lots of others, so you'd have to use one of the proxy services mentioned above, assuming they haven't blocked those, too.
Keep in mind that corporate IT departments monitor traffic and which sites are being accessed by their users, so they can easily see what you're doing, and you might lose your job over it. You should ask yourself if that's a risk worth taking.
But if it's your own computer, then that site and others have been blocked there, probably in your hosts file, which you can edit to unblock it.
use a free proxy service like hidemyass.com , proxy.org , youhide.com , proxy4free.com
a free VPN service like Hotspot ( http://anchorfree.com/downloads/hotspot-shield/ )
