⚠ Outdated official binary release

Since 2019, IceCat is maintained only as source code. The last IceCat binary release was version 60.7.0, and is no longer supported. Guix and Parabola have up-to-date IceCat binaries. Please ask your distro to package IceCat.

GNU IceCat (originally GNU IceWeasel) is part of GNUzilla (the GNU version of the Mozilla Application Suite). GNU IceCat is based on the the current Firefox Extended Support Release (ESR), with removal of trademarked name, trademarked artwork, and proprietary components, and enhanced privacy settings.

However, IceCat is not a straight fork of Firefox ESR; instead, it is a parallel effort that works closely with and re-bases in synchronization on the latest Firefox ESR as the upstream supplier, with patches merged upstream whenever possible; although it should be noted that additional security updates are customized to IceCat occasionally.

Differences between IceCat and Firefox ESR

Important differences between Mozilla's Firefox and GNU IceCat is that IceCat has a focus on freedom and privacy (see settings.js for details).

Encrypted Media Extensions (EME) is not implemented: Whereas Firefox are being created such that they support Digital Restrictions Management (DRM) systems through their implementation of the Encrypted Media Extension (EME), GNU IceCat doesn't include an EME implementation as it opposes efforts to popularize and ease the dissemination of DRM technology.

History

GNU IceCat was formerly known as GNU IceWeasel but changed its name in 2008 to avoid confusion with Debian IceWeasel (who was rebranded back to Firefox in 2017 after Debian was being granted special permission from Mozilla ref).

The GNU IceCat developers dropped support for IceCatMobile on Replicant after version 38.6.0 because these builds are already provided by F-Droid. See Collection:Replicant for more information about IceCatMobile in the F-Droid repository.

GNU IceCat developers dropped support for macOS, and Windows, after version 38.8.0 in 2016: "Note that building binary packages for Windows and macOS currently requires non-free software, so we no longer distribute binary releases for those platforms."

Jjmpeg: jjmpeg is a hand-rolled object-oriented native Java binding for a number libraries in FFmpeg together with some re-usable high level components that make reading and writing media files trivial. The various C structures are represented directly by garbage collectable Java objects and native accessors. Functions take native objects directly simplifying the internal Java-side scaffolding.

Kid3: Kid3 lets you easily and automatically tag MP3, Ogg Vorbis, FLAC, MPC, MP4/AAC, MP2, Opus, Speex, TrueAudio, WavPack, WMA, WAV and AIFF files (e.g. full albums), while supporting both ID3v1 and ID3v2 tags.

Kodi: Kodi (formerly known as XBMC) is an award-winning media player and entertainment hub, featuring a 10-foot user interface for use with televisions and remote controls. It allows users to play and view most videos, music, podcasts, and other digital media files from local and network storage media and the internet.

This includes the creation of melodies and beats, the synthesis and mixing of sounds, and arranging of samples. You can have fun with your MIDI-keyboard and much more; all in a user-friendly and modern interface.

Lib-Ray Video Tools: LRVT is the reference implementation of Lib-Ray, a video standard for fixed media with no technical restrictions like encryption or region codes. It is proposed as a replacement for restricted formats like DVD and Blu-ray, and builds on existing open standards like HTML5 and MKV. The end result is a DRM-free format that supports interactive menus and video playback from a disc, flash memory card or other fixed storage.

Additionally, it contains the qt-faststart utility which rearranges Quicktime files to facilitate network streaming. This package also serves as a replacement for the former 'ffmpeg' package.

Mpd-configure: The mpd-configure bash script creates a valid configuration file for mpd, optimised for bit perfect playback of any digital audio file, including those of high resolution. With default settings the script uses the first available alsa audio interface by using its hardware address (in the form of hw:x,y), and has automagic procedures for things like the music directory and directory where files are stored, the number of items in the music direcory and the UPNP name. When multiple audio interfaces are found, the user is presented with a choice.

Mpd-monitor: `mpd-monitor` is a bash script which displays the properties of an audio stream as played by Music Player Daemon (mpd). Besides the common mpd meta values of the current stream, like title, artist and source (url), it displays the detailed audio properties of the source stream or file, the way mpd interprets it, and the way the stream is handled by alsa (and thereforehanded over to the DAC). It can be used as a real life bit-perfectness monitor.
