I want to programatically access the open tabs #document object by the Browser Console. I am in chrome://browser/content/browser.xhtml I fallow the docs in browser console: https://firefox-source-docs.mozilla.org/devtools-user/browser_console/index.html

Following the code: var newTabBrowser = gBrowser.getBrowserForTab(gBrowser.selectedTab); newTabBrowser.addEventListener("load", function() {

newTabBrowser.contentDocument.body.innerHTML = "

this page has been eaten

";

}, true); newTabBrowser.contentDocument.location.href = "https://mozilla.org/";

.contentDocument is null except if current tab is a page such as page about:config

Is there a way to allow chrome:// tab to access read only of the tabs #documents property using the console?

I understand that accessing it with javascript from the browser console would be a security issue. I want to bypass it to read, analize and compare dynamic data from the open tabs.
