"Add-on for Firefox that stores visited websites in a folder."
Mozilla Firefox with a set aim: to store the Internet pages you visit. And this it does by storing a virtual copy in a hard drive file. When you want to find them it`s very easy, because the program offers a screenshot album and a text search engine.
To add the pages you want to keep, just click on the right button on the green icon. Firefox will quickly open the file where they are stored.
