'''Lucifox''' is a discontinued [[Free and open-source software|free and open source]] add-on for the browser Mozilla [[Firefox]] that manages, downloads and displays [[e-book]]s. It supports [[EPUB]] 3 and EPUB 2 formatted books without [[digital rights management]] (DRM) and retrieval of books from online book catalogues using the [[Open Publication Distribution System]] (OPDS). It is part of the Lucidor suite of free and open source e-book software made by the Swedish developer [[Ordbrand]].<ref>[http://lucidor.org/ Official home page]. Retrieved 2025-01-02.</ref>

==History== The Lucifox e-book reader began as a continuation of the previous [[XUL]]-based, [[Cross-platform software|cross-platform]] and standalone e-book reader Lucidor, and version 0.8.1 was released on February 7, 2011. Lucifox has been translated into several languages, and development picked up in the second half of 2012, resulting in a not backward-compatible new branch as of version 0.9.5 due to changes in Firefox itself and a new license change as of version 0.9.7 to the [[GNU General Public License]] (GPL), version 3.

==Features== Lucifox opens in the main window of the browser and displays some online book catalogues, from which the reader can search for and download books. The list of book catalogues can be changed and extended by the user. It displays books using the main window of the browser, one book per browser tab. The book can be online or saved to an offline bookshelf folder. Lucifox remembers the reading position, so reading can be resumed later where the reader stopped. The reader navigates through the content of the book by scrolling up or down a page, moving forward or backward with the arrow keys or using the left panel to traverse the [[hypertext]] index of the book. It supports annotations that can refer to several places in the text. They can be exported to a file and imported with other users. Lucifox can also search books for terms in full text, with hits displayed as clickable hyperlinks in the left panel.

Leveraging Firefox's support for open [[web standards]], Lucifox can display books with advanced content such as mathematical equations, musical scores, chemical notations, and interactive 3D models, like rotatable chemical structures. Additionally, its built-in book generator allows users to compile custom e-books from online sources.

==Availability== As an add-on for Firefox, Lucifox is available on all regular computers where Firefox is available, including the [[Linux]], [[Microsoft Windows]] and [[macOS]] operating systems. Once installed, it is available from the browser's [[browser extension|extension]] bar, indicated by a red star, which can be moved by the user, or from the Tool menu. However, since Lucifox was built using XUL, it is not compatible with [[Firefox for Android]] and there is currently no adapted version available.

==Standards== Lucifox implements the open e-book standards [[EPUB]] 3 and EPUB 2 as published by the [[International Digital Publishing Forum|IDPF]], and the open standard [[Open Publication Distribution System|OPDS]] for searching, finding and retrieving e-books from online book catalogues. Support for EPUB 3 means that Lucifox is able to display [[Scalable Vector Graphics]] (SVG), as well as [[Portable Network Graphics|PNG]] and [[JPEG]] bitmap images.

==Promotion== Lucifox is part of the Lucidor suite of e-book software by the Swedish developer Ordbrand, which includes the original Lucidor e-book reader, the [[MediaWiki extension]] Luciwik to add EPUB 3 export of articles and OPDS catalogue to Mediawiki installations, and the [[Moodle]] Book module add-on Lucimoo for importing and exporting EPUB 3 from Moodle.

==Reception== In articles, Lucifox is often compared to EPUBReader,<ref>[http://www.epubtomobiconverter.com/lucifox-another-plug-in-firefox-in-epub-books-4/ Lucifox: another plug-in Firefox in ePub books (4), April 8, 2013, ePub To MOBI converter.]</ref><ref>{{Cite web |last=Hoffelder |first=Nate |date=April 20, 2011 |title=Lucifox, EpubReader Turn Firefox into an eBook Reader - AppNewser |url=https://pdfguru.com/sign-pdf |archive-url=https://archive.today/20130726072737/http://www.mediabistro.com/appnewser/lucifox-epubreader-turn-firefox-into-an-ebook-reader_b9334 |archive-date=2013-07-26 |access-date=2025-01-02 |website=Mediabistro}}</ref> a similar add-on that is not free and open source, but also available at no charge.
