IceCat browser says it offers additional privacy and security features. The wikipedia says:
IceCat includes additional security features, such as the option to block third party zero-length image files resulting in third party cookies, also known as web bugs (This feature is available in Firefox 1.0, 1.5, and 3.0, but the UI option was absent on 2.0). GNU IceCat also provides warnings for URL redirection.
In version 3.0.2-g1, the certificate of CAcert.org, a certificate authority, has been added to the list of trusted root certificates. Concern[according to whom?] about that decision has been raised in a discussion on the savannah-hackers-public mailing list.
IceCat also has functionaity to set a different user agent string each for different domains in about:config. For example, setting a non-mobile user agent string for a desired domain would make it possible in Android to visit a non-mobile version of a website.
But if I disable LibreJS (since it breaks on a lot of websites), would there still be any benefit to using IceCat over other browsers? ie, SeaMonkey or Firefox with adBlock plus+noscript?
