Every time I try loading I get the following error "Firefox can't find the file at chrome://browser/content/www.facebook.com." I tried clearing all my history including cache and cookies and it still happens. To the best of my knowledge I haven't installed any new addons or anything of the sort. I've also checked to see if my browser is up to date. Does anyone have any ideas? Edit: I can get onto facebook when I google it and follow the link from the search result. But I can't type the address directly into the address bar at the top.
