FireFox Add-on permissions

Add-ons Development
#1

I am building an add-on as a project for Firefox using JPM and was
wondering how I could enable indefinite permissions for the user?

e.g.

I have the below code which prompts the user for permission on every website:

function HTT(theBody,theIcon,theTitle) {
var options = {
body: theBody,
icon: theIcon
}

if (!(“Notification” in window)) {
alert(“This browser does not support HTT notifications”);
}

else if (Notification.permission === “granted”) {

var n = new Notification(theTitle,options);
Date.now() + 30000;
//setTimeout(n.close.bind(n), 4000);

}

else if (Notification.permission !== ‘denied’) {
Notification.requestPermission(function (permission) {

  if (permission === "granted") {
    var n = new Notification(theTitle,options);
    Date.now() + 30000;
    //setTimeout(n.close.bind(n), 4000);
  }
});

}

}

What I would like to do is ask for permission once ONLY. How could I achieve this as I have tried a number of different options?

FYI - The purpose of the add-on is the display a notification, but this is the permission side of the code.

Thanks

I don’t quite get what you’re trying to do. Is the idea that the alert in your code is only shown once? Once per domain, once per page, something else?
