FIREFOX - cannot access any sites
I have a windows 7 home network with two computers. Firefox is set up exactly the same on both computers. One computer suddenly cannot access any websites (usual cannot access message). Internet explorer and MS outlook (for email) work fine. I have checked the usual stuff like firewalls (using Zonealarm) even with the firewall & Avirus off it still will not connect to ANY website.

Configure firewalls so that Firefox can access the Internet {web link}
Hi Fred, yes I have already tried these and all the obvious things. There are only 2 machines on the peer-to-peer network they have both their settings exactly the same as far as I can see but one of them refuses to connect to any website - whereas IE on same machine can and emails are OK - just firefox! Turned off firewall (Zonealarm) still no!

Start Firefox in Safe Mode {web link}
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?
