How to reuse same addon for your own domains?

Means that, you don't need to publish your own addon, you can reuse above link in your own domains/applications!

You should copy/paste following code in your own webpage/domain (HTML/PHP/Python/etc.):

// request addon to enable screen capturing for your domains
window.postMessage({
	enableScreenCapturing: true,
	domains: ["www.yourdomain.com", "yourdomain.com"]
}, "*");

// watch addon's response
// addon will return "enabledScreenCapturing=true" for success
// else "enabledScreenCapturing=false" for failure (i.e. user rejection)
window.addEventListener("message", function(event) {
	var addonMessage = event.data;

	if(!addonMessage || typeof addonMessage.enabledScreenCapturing === 'undefined') return;

    if(addonMessage.enabledScreenCapturing === true) {
    	// addonMessage.domains === [array-of-your-domains]
    	alert(JSON.stringify(addonMessage.domains) + ' are enabled for screen capturing.');
    }
    else {
    	// reason === 'user-rejected'
    	alert(addonMessage.reason);
    }
}, false);

How to Deploy?

1. Signup here:

4. Make XPI of the directory.

[sudo] npm install jpm --global

jpm run -b nightly 		# test in Firefox Nightly without making the XPI

jpm xpi					# it will create xpi file

Follow all steps. Read them carefully. This is hard/tough step to follow. Select valid browsers. E.g. Firefox 38 to Firefox 45. And submit your addon for "review".

It will take 2-3 hours for a Mozilla guy to review your addon. Then it will be available to public.
