GNU IceCat

Free and extensible Web browser based on Firefox

GNU IceCat is a Web browser derived from Firefox with a focus on user freedom. The most notable changes center around the removal of anti-features such as advertising and DRM, protection against browser fingerprinting, and the inclusion of the LibreJS browser extension, which blocks non-free JavaScript on websites.

Each version of GNU IceCat is built from the latest long-term support (LTS) version of Firefox, in contrast to LibreWolf, which tracks the very latest version instead. As such, GNU IceCat is relatively stable, only receiving new features from Firefox after a new LTS version comes out, while LibreWolf always has the latest features.

Browser extensions (also known as browser add-ons) are small programs that extend the functionality of your Web browser, including enhanced privacy features.
