Hi, I just started using Mozilla Firefox, and my Internet Explorer stopped working. I've gone into Windows Firewall and allowed the following servers already:FTP, HTTP, and HTTPS.
I recently opened some ports, those of which I have forgotten, that didn't work so I deleted them. Also I have McAfee - Personal Firewall Plus (2006) running on my computer, and I don't know what ports to open to allow my Internet Explorer to work. I'm asking this because I have recently downloaded some programs that access the internet through IE and they won't work. Thanks. ^-^
Mrs. Dee23, I installed FF then IE stopped working.

Did you start using Firefox because IE stopped working, or you were using FF and then IE stopped working.
If the latter, then uninstall FF and check to see if IE will work again.

Otherwise, check the settings for IE (Tools>Internet Options) to see that there's nothing blocking it.

Check your Advanced settings in your Firewall (both windows and McAfee) to make sure it's not blocking IE. Make sure it's not just blocking the ports that IE may use etc, but that the actual application itself is not blocked.

If you meant that IE stopped working in terms that it won't load ... then there may be a problem with the actual application itself. You may need to reinstall the it or get updates for it etc.
If you don't have the latest IE, download it to see if it makes a difference.

Cheers.

try uninstalling FF, and then see if it makes a difference to IE.

first off only run one firewall if 2 they well conflict and only use firefox it better then ie
