Using the following code sample,
:<pre>
:// Get browsers object
:var browsers=document.getElementById('content').browsers;
:var numBrowsers=browsers.length;
:
:for (var i=0; numBrowsers>i; i++)

: var thisURI=browsers[i].currentURI.spec;
: // do something with it.
:}

The person can get the titles too using the .contentTitle tag.

:<prefwidnow> can contain any control, just like a regular window. Some of them can be tied to a preference so that the preference is automatically updated as the control is manipulated. Others, like <listbox>, cannot be so tied, but one can always write a script that updates preferences explicitly, via nsIPrefBranch interface.

:You should be able to use a XUL template to display feeds, although you may have to write the feed data to an RDF datasource first.

:Loading remote DTDs for XML documents is currenty not yet supported in XUL.:;The following bugs were reported on this issue.:;https://bugzilla.mozilla.org/show_bug.cgi?id=22942:;https://bugzilla.mozilla.org/show_bug.cgi?id=133698 === [http://groups.google.com/group/mozilla.dev.tech.xul/browse_thread/thread/46c956df329be561/0cc354d668e2a3d9#0cc354d668e2a3d9 When loading an XSLT stylesheet into an XML I get the error: "Error loading stylesheet: An XSLT stylesheet load was blocked for security reasons."] === :That error is from a security check that has been put up to safeguard against cross-site-scripting attacks.
:A scheme is in development to allow servers to open up their site for cross-site access, but that's not yet done.

:Unfortunately, no simple solution to this was posted. A workaround is to open the content in a new window using "window.open" and send titlebar=”no” as one of the flags in the 3rd argument.

:Attributs such as left="100" or top="200" look as if they're integers but they are actually handled as strings.
:To use them as integers use JavaScript's [http://www.w3schools.com/jsref/jsref_parseInt.asp parseInt()] function.

From [http://www.croczilla.com/~alex/xulplanet/elemref/ref_button.html#attr_icon XULPlanet.com reference]:
:This attribute should be used to set the usage for common buttons. Some platforms display these buttons with a small icon indicating their usage. This should be used in place of the image attribute. Possible values include: accept, cancel, help, open, save, find, clear, yes, no, apply, close, print, add, remove, refresh, go-forward, go-back, properties, select-font, select-color, network. If you are using a button that matches one of these common usages, use the icon attribute to indicate this.

There may be a few ways to implement this:
#By building your menupopup from an RDF datasource, which could be generated on the server.
#By getting data (e.g. JSON string) from the server, parsing it on client, and building the menupopup using DOM methods (such as document.createElementNS).
#By getting data as XML from the server. (server can just send the XUL code to use for popup - alternatively it can send generic XML describing the attributes of the items in the menu and you generate the XUL on client by applying an XSLT transform.)
=== [http://groups.google.com/group/mozilla.dev.tech.xul/browse_thread/thread/c38b314ec14bf039/b3fafe8e0a90102c#b3fafe8e0a90102c Can I change a XUL tree cell/row/item background color with Javacript?] ===
To set the background color you need to set the property for the cell/row and not for the item.
An example of this is:
:<pre>
:selectedtreeitem = tree.view.getItemAtIndex(tree.currentIndex);
:electedtreeitem.firstChild.setAttribute('style', 'background: #FF0000');

To specify a function to run when the window is loaded,add the following code between the script tags in the XUL file:
window.addEventListener("load", function(e) { startup(); }, false);
Similarly, for onunload use the code:
window.addEventListener("unload", function(e) { shutdown(); }, false);

An event is initiated when the application starts up and when the profile is changed. For more information please look at the following link: [http://lxr.mozilla.org/mozilla/source/toolkit/mozapps/extensions/src/nsExtensionManager.js.in#2703 nsExtensionManager.js]

Python has full support for variants. Pass a Python string/int/etc to the method requiring an nsIVariant. A Python object is convered when implmenting an interface taking an nsIVariant.
=== [http://groups.google.com/group/mozilla.dev.tech.xul/browse_thread/thread/b8916415bc0fa019/9c7fd67b21949317#9c7fd67b21949317 How do I close the "showPopup" which is automatically opened when the "oncontextmenu" event is called?] ===
If you have a similar code base as the following:
:<pre>
:onBookmarkContextMenu: function(event, id) {
: document.getElementById("bookmarkPopup").showPopup(document.getElementById(id),
: event.screenX + 6, event.screenY + 6, "popup", "bottomright",
: "bottomright");
:
:}
:</pre>
Use the hidePopup() function to solve this issue.

An example of this is this:
:<pre>
:// Associate the progress listener for a "browser" to a listener object
:
:browserObject.addProgressListener( listObj,
: Components.interfaces.nsIWebProgress.NOTIFY_STATE_WINDOW );
:
:// Remember to define the object, something like this:
:
:listObj = new Object();
:
:listObj.wpl = Components.interfaces.nsIWebProgressListener;
:
:listObj.QueryInterface = function(aIID) {
: if (aIID.equals(listObj.wpl) ||
: aIID.equals(Components.interfaces.nsISupportsWeakReference) ||
: aIID.equals(Components.interfaces.nsISupports)) return this;
: throw Components.results.NS_NOINTERFACE;
:
:}
:
:listObj.onStateChange = function(aProgress, aRequest, aFlag, aStatus) {
: if (aFlag & listObj.wpl.STATE_START) {
: // This fires when the load event is initiated
: } else {
: if (aFlag & listObj.wpl.STATE_STOP) {
: if ( aFlag & listObj.wpl.STATE_IS_WINDOW ) {
: // This fires when ALL load finish
: }
: if ( aFlag & listObj.wpl.STATE_IS_NETWORK ) {
: // Fires when ALL load are REALLY over,
: // do something "final" here
: // (my two cents)
: } else {
: // This fires when a load finishes
: }
: }
: }
: return 0;
:
:}
:
:// This fires when the location bar changes i.e load event is confirmed
:// or when the user switches tabs
:listObj.onLocationChange = function(aProgress, aRequest, aURI) {
:
:// do whatever you want to do
:return 0;
:
:}
:
:// For definitions of the remaining functions see XulPlanet.com
:listObj.onProgressChange = function() { return 0 };
:listObj.onStatusChange = function() { return 0 };
:listObj.onSecurityChange = function() { return 0 };
:listObj.onLinkIconAvailable = function() { return 0 };

Use the following snippet of code to add a new element under an existing element:
var elem = document.getElementById(XUL_ELEMENT_ID);
var node = document.createElement(XUL_ELEMENT_NAME);
node.setAttribute(ATTRIBUTE, VALUE);
node.setAttribute(ATTRIBUTE, VALUE);
elem.appendChild(node);

The sidebar's content is a separate document, so you should use document.getElementById("sidebar").contentDocument.getElementById(...)
This is something you could see using the DOMi.

objScriptLoader = Components.classes["@mozilla.org/moz/jssubscript-loader;1"].getService(Components.interfaces.mozIJSSubScriptLoader);
objScriptLoader.loadSubScript(strURL);
