Five years ago yesterday, Netscape released the Communicator source code. In the years since then, Mozilla.org community members have hammered on the code to create an extraordinary browser that leads the world in standards support and is a platform for other browsers as well as other products.
By coincidence, the 200,000th bug was logged in the bugzilla bug tracking system on the five year anniversary of the source code release. Although bugzilla tracks many components and tools other than the browser and includes features and duplicates as well as unique and real bugs, the magnitude of that bug number is amazing. Many, many bugs have been found and fixed over those five years, making Mozilla a solid and stable tool. A number of these fixed bugs include security exploits that remain unpatched and troubling in other browsers.
Happy birthday, Mozilla!
