Firefox has hit over 1 billion downloads worldwide since then and continues to fight market share away from the clear leader, Internet Explorer.
"We've managed to keep Microsoft honest and forced them to release newer versions of their browsers," says Mozilla's Christopher Blizzard. "Firefox's presence was a large factor in Apple being able to ship a browser to its user base as the Mac came back to the market. We've made it possible for third party browser vendors like Google to enter the market."
