Re: Firefox can't find the server at www.facebook.com.
This was a server crash that happened to Facebook a few days ago. After all, they do have a lot of people on at one time. It should be fixed by now, but sites cannot always be assured not to crash at any moment. To determine if a site is down or if your computer/browser is having a problem, go to http://downrightnow.com/ . If it wasn't just a crash and Facebook still doesn't work, please reply.
