Firefox Scholar aka SmartFox
SmartFox will enable users, with a single click, to grab a citation to a book, journal article, archival document, or museum object and store it in their browser. The Center for History and New Media is building an open-source package of tools for libraries and museums that will work right in the web browser, where most research is now done. We are calling the project SmartFox: The Scholar's Web Browser, and it will enable the rich use of library and museum web collections with no cost - either in dollars, or probably more importantly, in secondary technical costs related to their web servers--to institutions. This set of tools will be downloadable and installable on any of the major open-source browsers related to the increasingly popular Firefox web browser: Firefox itself, Mozilla, and the latest versions of Netscape and the AOL browser (all based on the Firefox code base).
Little bit confusing name, there is already browser with such name:
