Internet & Networking Now this is a subject sure to cause some discussion among all of you. LifeHacker's Adam Pash is arguing that Chrome has overtaken Firefox as the browser of choice for what he calls 'power users'; polls among LifeHacker's readership indeed seem to confirm just that. He also gives a number of reasons as to why this is the case.

Also, JavaScript performance will jump from 0.5 to 0.8 Chromes for sunspider and from 0.25 to 0.6 Chromes for v8bench (arewefastyet.com).


These 30% to 50% jumps in performance shown on arewefastyet.com are merely the jumps in Firefox 4 performance since July 28 to September 15.

They are not the jumps in performance from Firefox 3.6 to Firefox 4, which has seen a performance improvement of over 250% in all.

The speed improvement from gecko 1.9 to Gecko 2, when it is released, will be far more dramatic than the picture you paint.

Having no more features than Chrome and being slower than Chrome


The first is decidedly incorrect, the second is yet to be determined, it is still an open question, except for the performance of rendering and compositing on not-too-old hardware, where Firefox 4 is many times faster than Chrome.

About speed, I'll give you my rates at Bubble Bobble at:
http://benfirshman.com/projects/jsnes/
Firefox 4 Beta 6: 15 FPS. Chromium 6: 60 FPS. Opera: 10.62: 60 FPS.

About features, I think browser market share trends are a strong indicator of features demand/satisfaction. In this field, Chrome is growing exponentially while Firefox has converged at 25%. This tells me that, compared with Chrome, Firefox has no more features relevant to the average user.

Firefox 4 will still be slower than Chrome for sunspider and v8bench, and has not more relevant features for the average user than Chrome. Which is what I was trying to communicate with the first message.

Nah, the JSNES slowness issue was just a bug that's been fixed weeks ago. I guess the release process made the fix not enter beta6, but right now on a build from today I'm getting 45 FPS on my laptop.

Beta 6 does not yet have the JavaScript engine (J√ĄgerMonkey) integrated. It will be released with beta 7 and runs the SNES emulator perfectly fine with 60 FPS.

Firefox 4 will use both Jaegermonkey plus Tracemonkey, working together. The latest beta release Firefox 4.0b6 has only Tracemonkey, Jaegermonkey wasn't yet integrated at that release.

The gold plotline is Tracemonkey ... this is what you would have seen in Firefox 4.0b6.

The black plotline is Jaegermonkey, and the purple plotline is Jaegermonkey plus Tracemonkey. The latter is what you will get in the final release of Firefox 4.0.

If trends continue, Firefox with Jaegermonkey plus Tracemonkey will overtake Chrome for sunspider in perhaps two weeks time.

If trends further continue, Firefox with Jaegermonkey plus Tracemonkey will overtake Chrome for v8bench in perhaps four to six weeks time.

Exactly what performance Firefox 4.0 will have on release is still an open question, but it is by no means impossible that it will be faster than Chrome (even according to Google's own v8bench benchmark).

Firefox has a number of better features than Chrome as far as the average user goes, extension like this one not being the least of them:
