NAME

icecat - IceCat - GNU version of IceCat browser  

SYNOPSIS

icecat [ ,options /... ] [,URL/]  

DESCRIPTION

Gnuzilla IceCat is an open-source web browser, designed for standards compliance, performance and portability.

GNUzilla is the GNU version of the GNU suite, and GNU IceCat is the GNU version of the IceCat browser. Its main advantage is an ethical one: it is entirely free software. While the IceCat source code from the GNU project is free software, they distribute and recommend non-free software as plug-ins and addons.

In addition, GNU IceCat includes some privacy protection features, included in a separate addon:

Some sites refer to zero-size images on other hosts to keep track of cookies. When IceCat detects this mechanism it blocks cookies from the site hosting the zero-length image file. (It is possible to re-enable such a site by removing it from the blocked hosts list.) Other sites rewrite the host name in links redirecting the user to another site, mainly to "spy" on clicks. When this behavior is detected, IceCat shows a message alerting the user.

Origin of the name

The name IceCat was coined to show our relationship to the GNU IceCat browser. Ice isn't Fire and a Cat isn't a Fox, so it is clearly a different package (we don't want GNU blamed for our mistakes, nor cause confusion with their trademarks), but is equally clearly intimately related (of course nearly all of the work comes from the GNU foundation effort, so we want to give credit).
