I recall using a Firefox plug-in that saves a web-page to disk, including all dependencies, such as images, CSS, Javascript, etc.
Just can't recall the exact name of it.
I think it was called "snapshot" or something, but I've been Googling for half an hour and still can't find it.
Can anyone help?

In my Firefox the menu item
File->Save Page As->Web Page, Complete
saves all javascript and images and css. No plugin required.
