Editorial Hands up if you use Firefox. Have used it? Know about it? Heard of it? 'Sites up and down the World Wide Web today will be celebrating five years of Firefox. When I sat down to write this I worried about having to list the history of its features and landmark events and the news of the past five years. Other sites will be comprehensively doing that, there is nothing I can add to that list that Google can't surmise. Instead I will be telling you what Google does not know, my story of Firefox and what Firefox has meant to all of us.

So I installed all versions of Firefox with fresh profiles and tested javascript performance with the Sunspider test (which is a test created by the Webkit team, just to make sure it is not favorrable to Mozilla...):

Result is that performance has been improving greatly over time and is still steadily improving. You forgot to mention that SpiderMonkey, the js engine is also powered by a JIT compiler (activated between 2.0 and 3.0 as the graph clearly shows).

So yes, currently V8 *is* faster but not to a point where it makes a real difference with web apps. The latest Chrome builds are like 70% faster than the latest Firefox trunk builds in Javascript, down from 200% a year ago, but the real challenge is having IE that is like 10000% slower and is slowing down progress for the Web itself.

And sorry, but not everybody is turning towards webkit, a few visible browsers (Chrome, Safari) use Webkit because it is easily embeddable, but there are tons of applications, some way more complex than a browser, using the Mozilla platform, here is a list of some prominent ones:

I wouldn't hold my breath for a switch to V8 any time soon, Spidermonkey si not just fast, it is accurate...
