I've been running knoppix 3.8.

The included version of konqueror 3.3.2 runs fine and goes to any internet website.

However firefox (version 1.0.2) tops working after the first 10 or 12 minutes. It comes up with the message with any internet website "The connection was refused when attempting to connect to <internet website". Replace the <internet website> with any website. Funnily enough it's possible to connect to the local router using an ip number only and other websites using ip numbers.

Thanks
