I have been experiencing a bit of a problem with Chrome over the last couple of days where it doesn't want to access Facebook.

When I open Chrome it works fine for a while and then if I were to refresh the page it would give me the Chrome 'This webpage is not available' message.

This problem only persists when using the proxy and doesn't occur at all when not on the proxy. I have also tried different browsers (IE9 and Firefox 9.01) but it doesn't occur in any of them. This problem goes away for a while when I restart Chrome, only to happen again a couple of minutes later.

I have tried deleting the cookies for Facebook without restarting Chrome, but to no avail.

I am using Windows7 with Chrome 17
