Modules - Archive of obsolete content
the module system used by the sdk is based on the commonjs specification: it is implemented using a loader object, which handles all the bookkeeping related to module loading, such as resolving and caching urls.
...however, the following example shows how it can be used to load scripts from other locations: const { classes: cc interfaces: ci } = components; var instance = cc["@mozilla.org/moz/jssubscript-loader;1"]; var loader = instance.getservice(ci.mozijssubscriptloader); function loadscript(url) { loader.loadsubscript(url); } when a script is loaded, it is evaluated in the scope of the global object of the script that loaded it.
...for instance, it does not know how to handle relative urls, which is cumbersome if you want to organize your project hierarchically.

Building the WebLock UI
this is a bit more complicated, because it requires that you work with the currently loaded page or provide other ui (e.g., a textfield where you can enter an arbitrary url) for specifying urls.
... the url that the addsite method expects is a string, so we can pass a string directly in from the user interface, or we can do a check on the string and verify that it's a valid url.
... in this tutorial, focusing as it is on the weblock functionality (rather than the ui), we'll assume the strings we get from the ui itself are urls we actually want to write to the white list: function addthissite() { var tf = document.getelementbyid("dialog.input"); // weblock is global and declared above weblock.addsite(tf.value); } this javascript function can be called directly from the xul widget, where the input string is retrieved as the value property of the textbox element.

...me is simply a skin file to be loaded into the xul file, but the chrome can also be used to load whole chromes, as when a <menuitem> in one window brings up a new chrome: <menuitem value="mozilla help" oncommand="window.opendialog('chrome://help/content/help.xul', '_blank', 'chrome,all,dialog=no')" /> in this example, the chrome url is being used to point to a chrome within the package hierarchy of the mozilla application.

What are hyperlinks? - Learn web development

...being human-readable, urls already made things easier, but it's hard to type a long url whenever you want to access a document.

Setting up your own test automation environment - Learn web development
