When I try to use internet explorer to reach a website I get the message internet explorer cant be used. The diagnosis says that HTTP port 80 is blocked by a firewall also port 443 and FTP port 21 are blocked. I really do know how to resolve this problem. Thanks Dean

Try installing the IEtab2 add-on from https://addons.mozilla.org/en-US/firefox/addon/ie-tab-2-ff-36/ it will let you use the IE rendering engine within firefox

just make sure to drag the ietab icon onto a suitable place within browser e.g. add-ons bar / status bar / address bar
