Accessing the DOM in a Firefox for Android add-on -

this sounds simple question, i've been going through mdn documentation of "firefox android" , can't seem figure out.

i'm trying build simple "firefox android" add-on, inserts script tag visited pages. i've tried following code (leaving out template boilerplate code):

function loadintowindow(window) {   if (!window)     return;    menuid = window.nativewindow.menu.add("insert", null, function() {         insertscript(window);     }); }  function insertscript(window) {      // none of these properties exist: window.document.body.innerhtml, window.body.innerhtml     // window.document.body.innerhtml = "<h1>this page has been eaten</h1>";      // var contentscriptstring = 'document.body.innerhtml = "<h1>this page has been eaten</h1>";'      // throws error "referenceerror: require not defined"     // var tabs = require("sdk/tabs");      // tabs.activetab.attach({     //  contentscript: contentscriptstring     // });      // throws error "typeerror: attach not function"     // window.browserapp.selectedtab.attach({         // contentscript: contentscriptstring     // }); }  function unloadfromwindow(window) {   if (!window)     return;      window.nativewindow.menu.remove(menuid); } 

the loadintowindow function being correctly called, since "insert" option added menu option, , option in turn correctly calls insertscript option when tapped.

however, i'm @ loss on how access window's dom in order insert script. i've tried options mentioned on page content scripts , browserapp property..

thanks,

william

looks can answer own question. after looking through browser.js, found following code works access current page's dom:

var contentwindow = window.browserapp.selectedbrowser.contentwindow; var document = contentwindow.document;  document.body.innerhtml = "<h1>this page has been eaten</h1>";
