Firefox connection problem
Since about 7 hours ago, whenever I try to use Firefox (3.5.7) nothing happens. 2 hours before that it worked fine. I can access the internet through IE and directly from other applications (Google Earth etc). I've run malware remover, virus scan, registry scan etc. etc., have restored to a point two days earlier and have re-installed Firefox, all to no avail.
Any ideas greatly appreciated.
