GNU IceCat is the GNU version of the Firefox ESR browser.
Extensions included to this version of IceCat:
* LibreJS
GNU LibreJS aims to address the JavaScript problem described in the article
"The JavaScript Trap" of Richard Stallman.
* JShelter: Mitigates potential threats from JavaScript, including fingerprinting,
tracking, and data collection. Slightly modifies the results of API calls,
differently on different domains, so that the cross-site fingerprint is not
stable. Applies security counter-measures that are likely not to break web pages.
Allows fine-grained control over the restrictions and counter-measures applied
to each domain.
* A set of companion extensions for LibreJS by Nathan Nichols
are pre-installed, and provide workarounds to use some services at USPS,
RSF.org, SumOfUs.org, pay.gov, McDonalds, goteo.org and Google Docs
without using nonfree JavaScript.
* A series of configuration changes and tweaks were applied to ensure that
IceCat does not initiate network connections that the user has not explicitly
requested. This implies not downloading feeds, updates, blacklists or any
other similar data needed during startup.
