Error when launching Firefox

Hi; I’m experiencing a problem when launching Firefox . Receive the following message;

Firefox can't establish a connection to the server at en-gb.start3.mozilla.com

I’ve removed and reloaded Firefox, but same problem.

The only thing I can think of that’s changed on the PC is that I’ve renewed & McAfe AntiVirus Plus (which also had to be removed then reloaded).

Any suggestions as to what’s the problem & how to fix?

Chosen solution

Your software Firewall (or even the McAfe AntiVirus) is likely blocking the Firefox 3.6.13 .exe from connecting online.

Configure firewalls so that Firefox can access the Internet - link


Firewall not Firefox for third word oops.

I've tried checking the firewall issue; removed and reinstalled Firefox several time; run multiple anti-virus programs looking for issues; and it still doesn't work. However, today Google Chrome began working as my internet connection; and it works beautifully using Firefox (Go figure!). However, when I again reinstalled the actual Firefox program, it still does not work; so I have once again removed it. I find this very interesting.
