There are many web browsers for Linux, but everyone has different needs, some prefer customizable browsers with all the wizz and bang of plugins and themes, while others prefer lighter browsers that don’t have so many features and add-ons. It is hard to find what browser you might need, which is why a large list of these browsers (With the addition of a summary and table identifying the Engine used, the company or developers who make the browser and which license/s the browser is under) is provided:

Mozilla Firefox and Firefox derivatives/forks

Mozilla Firefox

Engine Gecko
Company Mozilla Corporation
License MPL/GNU GPL/GNU LGPL/Mozilla EULA

Firefox is an Open-Source browser developed by the Mozilla Corporation and is considered to be the second most popular web browser in the world (Internet Explorer is the first). Firefox is said to be stable, secure and efficient. Firefox is still considered to be a browser worth using becuase of the infinite amount of extensions available. Many Linux and BSD distributions like Ubuntu, OpenSUSE and Mandriva already provide Firefox as a pre-installed application or an optional package. Some complain about Firefox’s speed, because of its slow load up times and general use.

Flock Browser

Engine Gecko
Company Flock, Inc.
License GPL, some components also LGPL+MPL
