On my laptop i have a weird problem, none of my web browsers can access the internet.
But msn messenger and Thunderbird are perfectly working. I have a wireless broadband connection. My guess is some viruses may block my port:80.

Check the proxy settings of browser. Does it match the settings of your mail problem e.g. – futureelite7 Nov 25 '09 at 10:05

I would suggest checking your DNS. Open command prompt and try to ping google.com, if that doesn't work try pinging 72.14.213.104, which is a google.com IP. If it doesn't work for the address, but it does for the IP, you probably have a DNS issue.

You could try to manually set your DNS to something new like 8.8.8.8 which is google's new DNS, or 4.2.2.2 (not google)
