mozilla firefox extension: creating a javascript library and using it in a HTML page

Question

I created a library in a firefox extension :

./components/main.js
./skin/icon.png
./install.rdf
./chrome.manifest

my main.js would use define a class calling a mozilla TCPScoket ( https://developer.mozilla.org/en-US/docs/Web/API/TCPSocket)

function MYLib() {}    
MYLib.prototype.doWork = function(arg1,arg2) { /* do something with TCPScoket */}

How should I use my library on the client side in the HTML ?

I'm looking for something like (?):

<html><head><script>
var mylib = MozillaApiThing.createNewInstance("chrome://myextension/", "MYLib");
 ....
 </script>(...)

You could try search on Google: "firefox extension github" since Github is full of open source, you might find something useful — Daniel Cheung

I tried that : I cannot find anything specific on github/MDN . Furthermore a large part on MDN seems outdated. — Pierre

chrome or resource (not in restartless) URLs are available as direct URLs (ie you can enter them into address-bar and they show up). Therefore you can use it as a simple script src

<script src="chrome://myextension/components/jsfile.js"></script>

Alternatively, you can read the JS file (ie with XMLHttpRequest or FileUtils.jsm or osfile.jsm) and then insert the content into the page with createElement('script'), textContent and appendChild()

Alternatively, you can try The message manager

Note: Inserted local script into the page will have the content page scope (no access to browser scope API)

not tested yet, but can use the Mozilla API (like TCPScoket ) without asking for the user's permission ?
