Scrapbook

is a Firefox extension, which helps you to save Web pages and easily manage collections. Key features are lightness, speed, accuracy and multi-language support.

Major features are:

* Save Web page
* Save snippet of Web page
* Save Web site (In-depth Capture)
* Organize the collection in the same way as Bookmarks tree
* Highlighter, Eraser and various page-editing tools
* Full text search and quick filtering search
* Text edit feature resembling Opera's Notes

You can access a tutorial here. It's intuitive enough, though, and I could create folders and save Web pages without reading the tutorial.
