What is Mozilla?

Mozilla is a global, nonprofit organization dedicated to making the Web better. We emphasize principle over profit and believe that the Web is a shared public resource to be cared for, not a commodity to be sold. We work with a worldwide community to create open source products like Mozilla Firefox, and to innovate for the benefit of the individual and the betterment of the Web. The result is great products built by passionate people and better choices for everyone.
