Why doesn't Firefox/IE connect to the internet?

Help me please! I have been using Netscape to connect to the internet, which I don't really like. I have internet connection and can ping any website, but for whatever reason Firefox/IE won't connect. It says "unable to connect to the internet" everytime I try for some reason. This happened a few weeks back first with IE, than couple days later with Firefox. However, Netscape has never had a problem so far. Please help me fix this problem. I hate using Netscape, since IE is my default browser. Thank you.

what can you ping? If you can ping by both name (www.yahoo.com) and ip (69.147.114.210), then it is not a firewall. the problem would be within the browser. If you can only ping by name it is most likely the anti-virus firewall, spyware, 3rd party browser extensions, wrong proxies. If you can only ping by ip, the flush your dns. ( goto the command prompt and type ipconfig /flushdns. the most common cause is the firewall though, especially if it's norton or mcaffe... if all fails, you may need to reset tcp/ip through the command prompt. it would depend on the version of windows...i assume you have windows. (on a mac, there is one fix for all not moving data issues, just create a new network location.if it's XP there is a regedit to reinstall tcp/ip by deleting winsock1 and 2. you can search for the xp winsock2 regedit for proper instructions, MAKE SURE you export the registry as a text file before deleting anything within the registry, however, i doubt you'll have to go that far

Check your firewalls, or proxy settings in IE.
