There’s not much contention that IE6 is an outdated browser and is not suited for the modern web. If you don’t buy that just on sheer merit, there’s no point to read the rest of this article.
Most informed articles addressing the issue have boiled “the reason why” down to the fact that those users can’t upgrade (restricted by work, slow computer, etc.)
However, I wonder how it would be to build an HTML/JavaScript browser (which is effectively what Firefox currently is) that embeds directly into IE6 by visiting a webpage.
A user loads IE6, sets his/her home page to “awesome-js-browser.com” and then navigates from within that page.
I would venture that this would more of a nuisance and a resource hog than anything, else I think Mozilla would have tried it …
or have they? …
