ScrapBook is an extension for the Mozilla Firefox web browser which adds enhanced scrapbooking, page saving, bookmarking, and notetaking functionality.
ScrapBook saves web pages in the local computer. However, it can be used in combination with a synchronization service so that the data is accessible from other devices.[1]
As Firefox no longer supports legacy add-ons since version 57, the development of ScrapBook has been stopped and it is now referred as "legacy ScrapBook". It still works in a Firefox fork that supports the legacy XUL/XPCOM framework, such as Pale Moon and Waterfox. There are also successor browser extension projects that provides similar features in modern browsers, such as WebScrapBook and ScrapBee.
