Mozilla Firefox

One of the main reasons why Firefox is our personal browser of choice is

because it’s an open source software project with a development community
that releases very helpful add-ons and tools to extend its capabilities beyond
a Web browser, turning it into a Web development tool, in many cases.

You can find Firefox add-ons at https://addons.mozilla.org/firefox.
You can find add-ons for just about everything from the appearance of your
Firefox browser to browser-based games. At the time of writing, Mozilla
reports that 2,139,478,273 add-ons have been downloaded from its Web site.

Web designers and developers easier, more efficient, and just more fun:
