Other (non-IE) browsers gain ground (on my site)

I have a little picture on the bottom of my home page that keeps some simple stats on who visits the site, what continent they come from, and what browser they're using. About a year ago, Microsoft's IE browser held almost a 100% footing. Now, non-Microsoft browsers have a 6.6% hold, which is partly a result of my switching to FireFox, the next generation (open-source, public license) browser. This browser gives you tabbed browsing, security, extensions, themes, and standards compatibility that Microsoft hasn't matched. There's something about everybody contributing to it that seems to work better than a few engineers. With 21 million downloads yesterday, and counting, FireFox seems to be spreading.
