GNU IceCat is the GNU version of the popular Firefox web browser.
Its main advantage is an ethical one: it is entirely free software. While the source code from the Mozilla project is free software, the binaries that they release include additional non-free software. Also, they distribute and recommend non-free software as plug-ins.
In addition, GNU IceCat includes some privacy protection features:
- 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.
