I've been trying to get to the web, but keep getting the above message, followed by, "Firefox can't establish a connection to the server at mozilla.com." IE connects just fine, so it's not a connection problem with my modem, or provider. I even tried typing mozilla.com, and nothing but the error message. This follows an incident before logging off last night, in which my firefox windows suddenly went full screen (no search window, toolbar, etc). What gives?
