IceCat — GNU version of Firefox browser
icecat [ options ... ] [URL]
GNUzilla is the GNU version of the Mozilla suite, and GNU IceCat is the GNU version of the Firefox browser. Its main advantage is an ethical one: it is entirely free software. While the Firefox source code from the Mozilla 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 Mozilla Firefox browser. Ice isn't Fire and a Cat isn't a Fox, so it is clearly a different package (we don't want Mozilla 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 Mozilla foundation effort, so we want to give credit).
The gNewSense BurningDog browser and the Debian IceWeasel browser are similarly derived from Firefox, also with the intent of being free software. Technically, however, these projects are maintained entirely independently of IceCat. (Previously, this GNU browser project was also named IceWeasel, but that proved confusing.)
Extensions included to this version of IceCat:
Blocks privacy trackers while in normal browsing mode, and all third party
requests when in private browsing mode. Based on Adblock Plus.
Adds a custom "about:icecat" homepage with links to information about the
free software and privacy features in IceCat, and check-boxes to enable
and disable the ones more prone to break websites.
Uses the native video player to play embedded videos from different sources
- Fingerprinting countermeasures: Fingerprinting is a series of techniques
allowing to uniquely identify a browser based on specific characterisics of
that particular instance (like what fonts are available in that machine).
Unlike cookies the user cannot opt-out of being tracked this way,
so the browser has to avoid giving away that kind of hints.
