Firefox announced it has reached 400 million downloads, PC Pro reported. The browser’s popularity has reached 28% market share in Europe and 15% globally, PC Pro noted.

For those unfamiliar with Firefox, here’s what Firefox says about itself:

“Mozilla Firefox is a fast, full-featured Web browser that makes browsing more efficient than ever before. Firefox includes pop-up blocking; a tab-browsing; integrated Google searching; simplified privacy controls that let you cover your tracks more effectively; a streamlined browser window that shows you more of the page than any other browser; and a number of additional features that work with you to help you get the most out of your time online.”

Web Design firms should always stay on top of developing trends in browser popularity and conduct testing to ensure cross-browser compatibility.

Give Firefox a try.  It’s simple to install.
