GNU IceCat 4.0 on Trisquel
|Stable release||24.0 (October 16, 2013) [±]|
|Operating system||GNU/Linux, OS X|
GNU IceCat, formerly known as GNU IceWeasel, is a free software rebranding of the Mozilla Firefox web browser distributed by the GNU Project. It is compatible with both the GNU/Linux and OS X (10.4 and 10.5) operating systems.
The GNU Project keeps IceCat in synchronization with upstream development of Firefox while removing all trademarked artwork. It also maintains a large list of free software plugins. In addition, it features a few security features not found in the mainline Firefox browser.
Origins of the name
The Mozilla Corporation owns trademark to the Firefox name and denies the use of the name "Firefox" to unofficial builds that fall outside certain guidelines. Unless distributions use the binary files supplied by Mozilla, fall within the stated guidelines, or else have special permission, they must compile the Firefox source with a compile-time option enabled that creates binaries without the official branding of Firefox and related artwork, using either the built-in free artwork, or artwork provided at compile time.
This policy led to a long debate within the Debian Project in 2004 and 2005. During this debate, the name "Iceweasel" was coined to refer to rebranded versions of Firefox. The first known use of the name in this context is by Nathanael Nerode, in reply to Eric Dorland's suggestion of "Icerabbit". It was intended as a parody of "Firefox." Iceweasel was subsequently used as the example name for a rebranded Firefox in the Mozilla Trademark Policy, and became the most commonly used name for a hypothetical rebranded version of Firefox. By January 1, 2005, rebranding was being referred to as the "Iceweasel route".
In August 2005, the Gnuzilla project adopted the GNU IceWeasel name for a rebranded distribution of Firefox that made no references to nonfree plugins. The first Gnuzilla IceWeasel release was based on the 188.8.131.52 version of Firefox. There was no release based on Firefox 184.108.40.206 or 220.127.116.11.
The term "ice weasel" appeared earlier in a line which Matt Groening fictionally attributed to Friedrich Nietzsche: "Love is a snowmobile racing across the tundra and then suddenly it flips over, pinning you underneath. At night, the ice weasels come."
Debian was originally given permission to use the trademarks, and adopted the Firefox name. However, because the artwork in Firefox used to have a proprietary copyright license that was not compatible with the Debian Free Software Guidelines, the substituted logo had to remain. In 2006, Mozilla withdrew their permission for Debian to use the Firefox name due to significant changes to the browser that Mozilla deemed outside the boundaries of its policy, changes which Debian felt were important enough to keep, and Iceweasel was revived in its place.
On 23 September 2007, one of the developers announced that the name would be changed to GNU IceCat from Iceweasel in the next release. This was to avoid confusion with Debian's separately maintained, unrelated rebranding of Firefox. The name change took place as planned and IceCat is the current name.

Releases usually keep up to date with the Mozilla Firefox source code.
Additional security features
IceCat includes additional security features, such as the option to block third party zero-length image files resulting in third party cookie, also known as web bugs (This feature is available in Firefox 1.0, 1.5, and 3.0, but the UI option was absent on 2.0). GNU IceCat also provides warnings for URL redirection.
In version 3.0.2-g1, the certificate of CAcert.org, a certificate authority, has been added to the list of trusted root certificates. Concern[according to whom?] about that decision has been raised in a discussion on the savannah-hackers-public mailing list.
