The ScrapBook extension saves pages on the local computer. Therefore, saved pages won't be accessible from a smartphone or other computers of the user. However it can be used in combination with other synchronization services that can sync the folder where ScrapBook stores its data.
The extension was initially developed at Murota Laboratory, which is a member of the Chair of Human Resource Development in the Department of Human System Science at Graduate School of Decision Science and Technology, Tokyo Institute of Technology. It is currently maintained by Gomita.
ScrapBook won the "Most Useful Upgraded Extension" award in Mozilla's 2006 "Extend Firefox" competition.
There were no more updates of ScrapBook since April 13, 2015 (Version 188.8.131.52-signed.1-signed). Different Clones were created, namely ScrapBook Plus, ScrapBook Plus 2 and ScrapBook Lite, but development of all of them discontinued.
Finally Danny Lin took over and created ScrapBook X, which is built on the source code of its successors. It keeps mostly the architecture of ScrapBook, but has added new features and bugfixes. The project also took over the development of several Firefox add-ons which extend the functionality of ScrapBook X.
These add-ons are:
- ScrapBook X MAF Creator converts the ScrapBook X data item(s) into the .maff format (open format that enables saving of whole webpages in a single file (actually renaming the .maff extension in the .zip extension will make this web page archive accessible even by web browsers that don't support the .maff format)), which can be opened with Firefox's MAF addon.
- ScrapBook X CopyPageInfo copies to clipboard the information of single or multiple ScrapBook X data items with the possibility to format it in pre-defined or custom formats, which is useful for creating formatted bibliography references, for example in BibTeX.
- ScrapBook X AutoSave captures automatically the web pages on browsing them.
- ScrapBook X File Converter converts other formats (.enex, .maff, .html+files_directory, .epub, .zip, etc.) into ScrapBook X export format or back, which can then be imported into ScrapBook or ScrapBook X. Allows also to backup the whole ScrapBook or ScrapBook X data folder.
WebScrapBook is the successor browser extension of ScrapBook X written in WebExtension and supports Firefox (Desktop and Android) and Chromium-based browsers. A collaborating backend server, which can be set up using the webscrapbook Python package, is required for several functionalities such as organizing captures in the sidebar. 
ScrapbookQ is a Firefox "Quantum" extension (i.e. for Firefox version 60 and higher), which helps you to save Web pages and easily manage collections. It is compatible with the old ScrapBook extension and supports managing captures in the browser sidebar.
Analysis by Max Planck Institute
The Max Planck Institute for the History of Science has published an article about Digital ScrapBooking (Digital Scrapbook – can we enable interlinked and recursive knowledge equilibrium?) where Scrapbook X is thoroughly analysed and discussed as an example of scrapbooking tool for scholars: « ... The Scrapbook-X has been analysed in detail, with the aim to understand its potential, as it seemed to be the closest feature-related component with the Scrapbook paradigm, furthermore it is implemented as a Firefox browser plug-in i.e. it can be smoothly integrated in a web-based research and discovery of resources with a standard browser application. ... ». The abstract of this article, even if it was of course not its purpose, describes actually pretty well what ScrapBook X is doing (and, to some extent, ScrapBook): « We investigate possible tools and approaches to develop a Digital Scrapbook, a virtual research environment inspired by the recursive nature of research for scholars where they can combine web and own resources into a new scholarly edition readily enabled for Open Access. Web resources are interlinked in the digital scrapbook by content capture and detail selection, rather than sole bookmark or link to resource URL, along with necessary accompanying metadata. We analyse several open source and commercial tools, with special focus on a Scrapbook-X Firefox Add-On, in order to match to desired Digital Scrapbook features. We further address the wider requirement context for development of such Digital Scrapbook environment, discussing both technical and user experience dimensions. We conclude with a recommendation on how to approach the development and operation of a Digital Scrapbook environment. »
