Was trying to access some ports on a customer’s website which someone mapped it to 79. 79 is normally used for finger. For Internet Explorer, it works out right. This doesn’t work for Google Chrome and Firefox (out of the box)
- Launch Firefox
- Go to the address bar and type about:config. Firefox will complain about some warranty just click ok or “I’ll be careful, i promise” button
- Anywhere inside the list of configurations, right click and say New –> String
- In the string value, enter network.security.ports.banned.override then click OK
- It will now ask you what port, say 79 or whatever port you need to have firefox access. Click OK.
- And try again to the website you want to access. These settings should remain forever.
