Scrapbook CHM Creator is an add-on for the excellent Scrapbook or Scrapbook+ extensions for Firefox which allows you to create a Windows compiled help (CHM) file, also known as HTML Help, from a stored web site. Windows compiled help has the nice advantage of storing the web page and all of its related attachments and linked pages in a single, compressed file, allowing you to backup and store your favourite web sites for future reference. You can still access external links from the compiled document, as well, and gain additional features such as a search facility.
This add-on requires the Scrapbook or Scrapbook+ extensions and access to a HTML Help compiler (freely available) in order to function.
Microsoft's HTML Help Workshop is available from http://msdn.microsoft.com/en-us/library/ms670169%28VS.85%29.aspx
