I've been developing an add-on for firefox where I needed to download the webpages that I visit and store it locally. How should I do this ? I've been trying with javascript but there seems to be no proper reference. I googled and found a sample code but this shows error that "Component.classes" is undefined. So can I actually do it with javascript ?

THE LINE IN THE CODE WITH ERROR :

var dir =Components.classes["@mozilla.org/file/local;1"] 

      .createInstance(Components.interfaces.nsILocalFile);

Hi, make a folder on your system for each site and go tot the site and Right Click and Save Page as ot give this a try  : http://www.httrack.com/ Note if the site has safe guards up it will not matter what you use and you can not gain access.

You can't use XUL code in a WebExtension, you can only use API calls.

Try to ask advice at the Add-ons forum, that forum is better suited for questions about developing extensions.
