Firefox plug-in that downloads a complete webpage?

Though ScrapBook can do the job, I think the following plugin is better. It saves the web page into a single file, which is more manageable. And it claims a "faithful save".

In my Firefox the menu item

File->Save Page As->Web Page, Complete 

saves all javascript and images and css. No plugin required.

Use ScrapBook
