The NYT has a good overview article on Firefox and its significance to Microsoft given that IE is now rather old, integrated too tightly into Windows, and poses such a security risk. I think Firefox is an amazing testimony to the possibilities of open source software. It strikes me that Firefox may become the new emacs: a program that I spend the majority of my time in, independent of any particular operating system, designed for extensibility, supported by a large and growing collection of extensions developed by the user community, and nicely done. It reminds me of the quote “Emacs is my operating system, and Linux its device driver.” I think a more appropriate variation might be “Firefox is my operating system and the web is my device driver”. Of course, all is foretold by signs in the heavens, there for those who know where to look.
