12 Gnuzilla IceCat is an open-source web browser, designed for standards
13 compliance, performance and portability.
14 GNUzilla is the GNU version of the GNU suite, and GNU IceCat is the GNU
16 version of the IceCat browser. Its main advantage is an ethical one: it
17 is entirely free software. While the IceCat source code from the GNU
18 project is free software, they distribute and recommend non-free soft‐
19 ware as plug-ins and addons.
20 In addition, GNU IceCat includes some privacy protection features, in‐
22 cluded in a separate addon:
23 Some sites refer to zero-size images on other hosts to keep track of
25 cookies. When IceCat detects this mechanism it blocks cookies from the
26 site hosting the zero-length image file. (It is possible to re-enable
27 such a site by removing it from the blocked hosts list.) Other sites
28 rewrite the host name in links redirecting the user to another site,
29 mainly to "spy" on clicks. When this behavior is detected, IceCat shows
30 a message alerting the user.
31 Origin of the name
33 The name IceCat was coined to show our relationship to the GNU IceCat
35 browser. Ice isn't Fire and a Cat isn't a Fox, so it is clearly a dif‐
36 ferent package (we don't want GNU blamed for our mistakes, nor cause
37 confusion with their trademarks), but is equally clearly intimately re‐
38 lated (of course nearly all of the work comes from the GNU foundation
39 effort, so we want to give credit).
