Firefox Extensions: Add Button to Nav Bar
By Ken Snyder, published 2011-11-02
Firefox JetPack has become the official Add-On SDK. The SDK makes it super easy to write and test Firefox extensions. It allows you to include your favorite libraries such as jQuery and use them in your extension.
One point of frustration is that the SDK only allows adding buttons to the add-on bar. But I want my extension to have a button on the URL bar!
There is a simple way to do it with the new SDK. The super-secret lines are below.
var {Cc, Ci} = require('chrome');
var mediator = Cc['@mozilla.org/appshell/window-mediator;1'].getService(Ci.nsIWindowMediator);
// ..
var document = mediator.getMostRecentWindow('navigator:browser').document;
var navBar = document.getElementById('nav-bar');
// create a toolbarbutton element and append itCheckout my full article on adding buttons to the URL bar in the Firefox Add-On SDK.
