Mozilla Firefox is a fast, light and tidy 
open source web browser. At its public launch in 2004 Mozilla Firefox 
was the first browser to challenge Microsoft Internet Explorer’s 
dominance. Since then, Mozilla Firefox has consistently featured in the 
top 3 most popular browsers globally. The key features that have made 
Mozilla Firefox so popular are the simple and effective UI, browser 
speed and strong security capabilities. The browser is particularly 
popular with developers thanks to its open source development and active
 community of advanced users.
