Question

I’m experimenting with a firefox plugin, but I’m new to this and wouldn’t mind a little push. If I wanted to write a simple plugin that’s nothing but a button and when the button is clicked, it displays an alert message like “hello” or something. How would the js for this add-on look like?

Edit: I’m also thinking, it probably doesn’t have to be a button as in a toolbar button, probably just a button that appears somewhere on a page and can be activated. But not sure if there’s any disadvantages to this method over using an actual toolbar button.

You could use the addon builder to make a restartless addon like this one, to do what you want, like so:

exports.main = function(options) {
  // create the toolbar buton
  var tbb = require("toolbarbutton").ToolbarButton({
    id: "extension-tbb-id",
    label: "Button Name",
    image: "http://...",
    onCommand: function() {
      alert("hello");
    }
  });

  // move the toolbar button to the navigation bar
  if ("install" == options.loadReason) {
    tbb.moveTo({toolbarID: "nav-bar"});
  }
}
