Lurk moar. A lot more. And I don't mean on 4chan. Learn more about what is going on with VNC. If you think Firefox can act as a viewer, you probably shouldn't be using VNC. At the very least make sure to use a strong password for the VNC server so you don't turn your machine into a public terminal begging to be abused. You need a client program to connect. If you are using RealVNC (I haven't seen anything specific mentioned, so I am just going throw info at you) it should have come with the client program if you downloaded the server.

"myip" is not supposed to be a literal hostname, but an indication of what one should enter in a destination for (a web client of some kind?) and where. Though the clients I have used do not use http, and all the is needed it [ip address]:[port number]
TL;DR: Fail.
