404cache
Provides links to cache copies if a 404 page error is received. Displays a yellow toolbar similair to the popup block message, that provides the option to check the page in web cache services.
Supported 
versions: Firefox 1.0 - 1.6 ALL
Notes / Comments: I know from the get-go that it would be triggered with ANY item that the server sends a 404 for. I want to offer functionality for both seeing if the page is unavailable or if a certain element is unavailable. However, I cannot figure out a way to check what the 404 is for. If anyone knows how to determine the difference between a full-page 404 or an element-404, please email me! Plenty of research suggested nothing helpful.
