| <ul><li>To go through all open tabs in a browser, you first need to get a reference to browser's window. If your code is executed from a <code>browser.xul</code> (in Firefox) overlay (for example it is a toolbar button or menu ''click'' handler), you can access current window via <code>window</code> pre-defined variable.

| | |
| If your code is executed from its own window (for example, Settings dialog), you can use <code>[[nsIWindowMediator]]</code> to get it.</li>
| |
| | |
| <li>Then you need to get the <code><tabbrowser></code> element. You can get it with <code>win.gBrowser</code>, where <code>win</code> is the browser's window from the previous step. You can use just <code>gBrowser</code> instead of <code>window.gBrowser</code>, if running from <code>browser.xul</code> overlay.</li>
| |
| | |
| <li>Now use <code>gBrowser.mPanelContainer.childNodes.length</code> to get the number of open tabs. Then use <code>gBrowser.getBrowserAtIndex()</code> to get a <code><browser></code> element. For example:
| |
| <pre>var num = gBrowser.mPanelContainer.childNodes.length;
| |
| for(var i = 0; i < num; i++) {
| |
| var b = gBrowser.getBrowserAtIndex(i);
| |
| try {
| |
| dump(b.currentURI.spec); // dump URLs of all open tabs to console
| |
| } catch(e) {}
| |
| }</pre>
| |
| </li>
| |
| </ul>

| | |
| To learn what methods are available for <code><browser></code> and <code><tabbrowser></code> elements, use [[DOM Inspector]] or look in [http://lxr.mozilla.org/seamonkey/source/toolkit/content/widgets/browser.xml browser.xml] and [http://lxr.mozilla.org/seamonkey/source/toolkit/content/widgets/tabbrowser.xml tabbrowser.xml] for corresponding [[Development resources#XBL|XBL]] bindings.
