Mozilla unable to connect

I installed Mozilla Firefox in my computer. However, it won't connect to the internet. After unsuccesfuly trying to open a web, a message shows up: "www.mozilla.org could not be found. Please check the name and try again." I check the connection settings under options, and it is on "Direct connection to the internet." I monitored the network activity, and the program doesn't even try to get on the net. I have a cable internet connection, and I'm using a router. However, the program doesn't work at my school network neither.
Any ideas of how to get Mozilla working?

did you have Zone Alarm installed on your machine at any time ?

 

hey check ur shaw connection cause latley shaws been up and down and also on ur other computers are they running explorer?
also did it work fine when u just had explore with the hub?

 

Yes I had zone alarm on my pc before...but not anymore

 

reinstall zone alarm.. set the access for mozilla to ALLOW internet access and try it out. If it works, then you're a victim of ZA's poor removal issue.
