In its last several releases, everyone's favorite Open Source browser has become an unstable mess of add-ons, plugins, and other hacks that chew up memory like a fat kid with a chocolate-dipped corn dog. In fact, just last week, SecurityFocus released news of a devastating exploit in Firefox 3.5.5 that they blame squarely on its unstable architecture.
From its infancy Firefox has been the product of collaborative effort, unifying code from hackers worldwide. But thanks to the Hayes Law, we see that there is a "sweet spot" to such a development style, and that Firefox has long since left it behind. In the chart below, we can see that the number of Firefox developers has increased exponentially since 2002, and that number will more than double in 2010.
But it's time to be honest: either Firefox, as a modern web browser, will have killer performance on 64-bit, multicore Intel chips or it's not worth downloading and installing. And since, as we have seen in the recent past, that Firefox is actually getting slower with each release, Firefox is certainly a waste of time for anyone who takes their web browsing seriously.
