I tell people that the history of Mozilla and Firefox is so one of a kind that it should not be used - ever - as an example of what's possible.
The Mozilla project has always been a project trying to bring together open source developers with commercial software developers and distributors.
The Mozilla Corporation is not a typical commercial entity. Rather, it is dedicated to the public-benefit goal at the heart of the Mozilla project, which is to keep the Internet open and available to everyone.
Over the history of the Mozilla project, it turns out that the product browsers exists on many different kinds of machines.
Some people might speculate that Opera couldn't compete by charging when AOL, Apple, Microsoft, Mozilla and most other browser developers give away software for free. Not so. Just the opposite is true,
My take is the Mozilla Foundation took a look at this and its reliance on the community and saw a willingness to create a commercial model, and they saw it as the most sustainable way to move forward. It's a way to kick-start adoption of their technologies.
I got bitten by the free software bug in February of 1998 around the time of the Mozilla announcement.
The biggest problem I used to have with Mozilla was crashes, pure and simple. The thing would just lock up and die, (for) no evident reason beyond computer spite.
With this reorganization, the Mozilla Foundation will look much more like the Apache Foundation than it currently does.
I'd rather use Windows and Internet Explorer in Hell than I'd use Linux and Mozilla Firefox in Heaven!
