IceCat free download for Mac


Version 38.8.0

Open-Source browser based on Firefox.

IceCat overview

IceCat is the GNU version of the Firefox browser. Its main advantage is an ethical one: it is entirely free software. While the Firefox source code from the Mozilla project is free software, they distribute and recommend non-free software as plug-ins and addons. Also their trademark license restricts distribution in several ways incompatible with freedom 0.

Privacy-Protection Features
  • LibreJS: GNU LibreJS aims to address the JavaScript problem described in Richard Stallman's article The JavaScript Trap
  • HTTPS-Everywhere: Extension that encrypts your communications with many major websites, making your browsing more secure
  • SpyBlock: Blocks privacy trackers while in normal browsing mode, and all third party requests when in private browsing mode. Based on Adblock Plus
  • AboutIceCat: Adds a custom "about:icecat" homepage with links to information about the free software and privacy features in IceCat, and checkboxes to enable and disable the ones more prone to break websites
  • Fingerprinting Countermeasures: Fingerprinting is a series of techniques allowing to uniquely identify a browser based on specific characterisics of that particular instance (like what fonts are available in that machine). Unlike cookies the user cannot opt-out of being tracked this way, so the browser has to avoid giving away that kind of hints

Version: 38.8.0
Similar to Firefox, it also supports copy/paste features in the preferences menu, syncing and importing data from other browsers. Like the most of open source products its design is simple and the app has no needless functions. IceCat as well as Firefox does not take up much RAM. This browser is okay for you if you have an old machine or not enough RAM.
