I'd like to implement a server socket in java:

Java or JavaScript? Because they have only the first four letters in

something linke the following example.

The problem is that the HTML has not the permission to execute
instruction

HTML does not execute anything. It is a _markup_ language.

serverSocket =
Components.classes["@mozilla.org/network/server-socket;1"].
createInstance(Components.interfaces.nsIServerSocket);

This is script code, executed by the JavaScript engine.

Question:
1 - how do I give it this permisison?

The script can request permission, and it can (not: must) be given by the
user:

2 - one solution I thought was to put the javascript code in a firefox
extension, to load, so it should have all needed permisison, but,
How can I call a java script function define in an extension
^^^^^^^^^^^
Again, the language is named "JavaScript" for a reason.

from an html page? - there's some particular syntax?

AFAIK, you cannot. If you could, this would allow any foreign Web site
to trigger your extensions which do not run in the sandbox like the
client-side script code of the Web site. Surely you do not want that
to happen.

Learn HTML before you learn J(ava)Script/ECMAScript.
