Sample:

If you try to browse http://www.yourhomepage.com:79 Firefox will cancel this request for your protection.
It does that by default whenever you use a port other than port 80 - the default website port.

Solution:

1. Open Firefox

2. Type [i]about:config[/i] in the browser address field and hit enter

3. Right click anywhere on the screen. An "menu" opens

4. Select "new > string"

5. Enter preference name as: [i]network.security.ports.banned.override[/i]

6. Enter string value as: [i]79 [/i](or whatever port number you want)

Done. Now you can access your website on a non-standard port.

Don't ask me how to do this with IE.
