title: Accessing the content of other tabs in a browser
body: <p>I am using Mozilla Firefox and I am trying to figure out a way to access the content of other tabs in the same window using JavaScript and the DOM (I am open to other techniques if exist).</p>
  <p><strong>E.g.</strong>, I want to run JavaScript code in <code>tab1</code> which can find the title of some other tab. Basically I need this so that I can identify a tab which has opened due an <code>href</code> in my current page without using <code>window.open</code> method. All I want is a simple hyperlink which opens a page belonging to the same domain as the current page (the page should be opened in a new tab). Now I want to be able to access this new tab from the current tab.</p>
