Recently, someone I know made the following comment on the post I wrote about Firefox crossing the 1 billion download mark:

If Firefox is so popular, how come it still can’t run the Windows Live OneCare scan from Microsoft??

The short answer to this is they don’t have to. Part of the appeal of Firefox and the other alternative browsers is that people have a choice and they also get access to the underlying code, which lets them change things to suit their needs. For an example of this, just look at the quality and quantity of Extensions available to Firefox users; IE8′s add-ons are just getting started and are likely not as developed at this point. In this particular case, I’d look at IE Tab, a solid extension which I’ve found does a fair job of simulating an Internet Explorer setup.
