GNUzilla and IceCat
GNUzilla is the GNU version of the Mozilla suite (SeaMonkey), 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 source code from the Mozilla project is free software, the binaries that they release include additional non-free software. Also, they distribute and recommend non-free software as plug-ins. In addition, GNU IceCat includes additional privacy protection features lacking in Firefox.
SeaMonkey Internet Suite
Community effort to develop the SeaMonkey all-in-one internet application suite. Such a software suite was previously made popular by Netscape & Mozilla, and the SeaMonkey project continues to develop and deliver high-quality updates to this concept. Containing an Internet browser, email & usenet client, HTML editor, IRC chat and web development tools.
Each component can be installed separately, so if all you want is the web browser you can install it without anything else.
Nice, simple and easy to use web browser. It displays web pages with the same speed and accuracy as other popular browsers, such as Safari or Firefox. It has been translated to over sixty languages!
Great, extensible web browser.
Flock: The Social Web Browser
Free, next generation web browser. The web, and the way people engage online, has evolved dramatically over the past decade. But web browsers - the application that fundamentally enables online experiences and services across ones' connected life - have not kept pace.
Flock is focused on fundamentally evolving the browser, bringing a refreshing new approach to how people use and participate on the web and simplifying social and web-based applications by bringing them one step closer to the user and integrating them directly into the browser.
When using Flock, people can easily discover, access, create and share videos, photos, blogs, feeds and comments across social communities, media providers, and popular websites.
