You can try this:

var tabs = require("sdk/tabs");
var { getTabForId, getTabContentWindow } = require ("sdk/tabs/utils");
var tab = require("tabs").activeTab;
var window = getTabContentWindow (getTabForId(tab.id));
var content = window.document.body.innerHTML;

But maybe this answer is better.

You can get the body of the currently-selected tab using the following (after DOMContentLoaded):

gBrowser.contentDocument.body.innerHTML

Note: This only works in a standard extension, not in the SDK.

The Add-on SDK doesn't allow direct access to the tab contents - the idea is that the add-on and the tab might end up living in different processes eventually. What you do is injecting a content script into the tab to get you the necessary data, something like this:

var tab = require("tabs").activeTab;
tab.attach({
  contentScript: "self.postMessage(document.body.innerHTML);",
  onMessage: function(data)
  {
    console.log("Tab data received: " + data);
  }
});
