Firefox launched on November 9, 2004. It took one year for Firefox to
reach 100 million downloads. One further year and it doubled to 200
million. One more year and it's doubled again to 400 million downloads.
Today, you all have done it once again. With your amazing efforts,
Firefox has reached 400 million downloads and demonstrated that not
even the world’s most powerful companies can keep people from a better,
safer, and faster Web experience. You all, the grass roots and the
heart of the Firefox movement, have helped hundreds of millions of
people find that better, safer, and faster Web.
We use it and love it. It's our browser of choice. We just hope Mozilla keeps it quick and efficient and avoids bloating it like some other browsers we know.
