As I was going on vacation where there is a limited internet connectivity, I thought it would be great if I could get read some of the webpages offline. But I did not want to save the pages on local manually. I found a good Firefox plugin for it - work offline.
Its really useful - when in offline mode, it serves the page if its available in its cache - similar to what is offered by IE's Work Offline feature.
So good for the Firefox lovers.
