unable to use firefox or gaim but konqueror is working fine

[gordonbp]

i am using Knoppix 3.9 from a cd.
i have a Aztech DSL-600E modem/router and when i open konqueror i am able to view remote web pages but when i open firefox 1.0.4 that came with the cd i am unable to load any page, same as for connecting to my ICQ using Gaim, nothing happens.
what is the problem? how can i make sure its not a network configuration problem? what do i need to adjust on the modem to allow the connections?

You need to disable ipv6 in Firefox. In the Navigation Toolbar type "about:config" (without the quotes) and then scroll down to the option network.dns.disableIPv6. double-click it so that the value is True. Exit Firefiox. restart and you should be OK. Sorry I can't help with the GAIM problem.
