NAME

6       icecat - IceCat - GNU version of IceCat browser
7

SYNOPSIS

9       icecat [ options ... ] [URL]
10

DESCRIPTION

12       Gnuzilla  IceCat  is an open-source web browser, designed for standards
13       compliance, performance and portability.
14
15       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
21       In addition, GNU IceCat  includes  some  privacy  protection  features,
22       included in a separate addon:
23
24       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
32       Origin of the name
33
34       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
38       related (of course nearly all of the work comes from the GNU foundation
39       effort, so we want to give credit).
