icecat

GNU IceCat, formerly known as GNU IceWeasel, is a completely free version of the Mozilla Firefox web browser distributed by the GNU Project. It is compatible with Linux, Windows, Android and macOS.
IceCat is released as a part of GNUzilla, GNU's rebranding of a code base that used to be the Mozilla Application Suite. As an internet suite, GNUzilla also includes a mail and newsgroup program, and an HTML composer.
Mozilla produces free and open-source software, but the binaries include trademarked artwork. The GNU Project attempts to keep IceCat in synchronization with upstream development of Firefox (long-term support versions) while removing all trademarked artwork and non-free add-ons. It also maintains a large list of free software plugins. In addition, it includes several security and privacy features not found in the mainline Firefox browser.
