Problem loading Pages with Firefox

I am unable to load any pages with Firefox. IE and my other interent programs are fine, as is Firefox on my other computer (same network.)

I ran system restore (to factory settings) last night, but it was working fine until this morning when I got dvr hooked up, which cut out the (cable) internet for about 5 minutes. But like I said, everything else is working.

I'm not running a firewall atm, as Zone Alarm has not worked properly (on either of my computers) for a few weeks now and I'm not using a proxy, unless my router counts ... ?

 

Problem solved! It was ZA blocking Firefox from accessing the net. Since my router has a firewall, I just uninstalled ZA and now Firefox works fine. =)
