I installed Redhat 9 on a computer to do some Linux dabbling.

Everything seems fairly functional. The gateway and DNS server IP's are correct.
From a network perspective I can ping other machines on my network. I can ping computers outside of my network by both IP and by host name so my connectivity and DNS resolution are both functional.

But, whenever I try to start Mozilla it says its starting and then it just disappears. I don't get any error message or explanation for why its not functioning.

Any clues?

TIA
