Its critics have pointed out that it’s taken three years to even approach a 1.0 version. I see their point, but I think they’re missing the amazing feat the Mozilla group has performed. If you look at the releases page, you’ll see a who’s who of Operating Systems. Not only does it support Windows, MacOS 9 and X.x, most flavors of Linux, most flavors of Linux, but also OS/2 and a myriad of others. On top of that concurrent development on those platforms, each build of Mozilla displays pages, with the exception of the fonts available on the system, the same. My site looks the same on Mozilla no matter if I look at it on Windows, Mac, Linux, an embedded version of Gecko (Mozilla’s rendering engine), or on my Solaris box. That is an amazing accomplishment that should make everyone who worked on the project proud.
Microsoft can’t get two versions of Internet Explorer to work the same. Their Mac and Windows browsers don’t even use the same codebase, and only really share a name. Mozilla is the first of its kind, and a great example of the power of a vibrant and mobile open source community.
