I was fairly excited when Firefox 4 was released three months ago. When I say excited, it means I considered it to be a useful, logical continuation of a successful browser series, which I have been using since release minus 0.2 or so. But when Firefox 5 debuted just a few short days ago, my only response was meh, who cares. Indeed, it you really wanted to describe underwhelming to someone without referring to Merriam-Webster, Firefox 5 ought to do it.
Firefox 5 is, on paper, a very good browser. Because Firefox 4 is a very good browser and the two are identical. And there's no justification to the numbering system, apart from what I'm going to rant against in this article.
