Firefox 4 Beta 7 Has Revved Up The Engines

Firefox 4 beta increases java speed

The new Firefox 4 Beta stands miles apart from the last official release, Firefox 3.6.  Recently they just acquired the Jägermonkey team’s JavaScript engine and it has given them a serious speed boost, not to mention some of the other improvements that they’ve incorporated.

Last week Mozilla posted the latest benchmarks for Firefox 4 Beta, and they are smoking fast.  When compared to the old 3.6 version of Firefox we’re looking at speeds up to 5 times faster.

This made me curious, so I pulled up the benchmarks for each modern browser.  If you though Chrome was fast, well it still is!  Firefox isn’t far behind though, and David Mandelin, Firefox Engineer, stated that it is going to get even faster before they release the official version 4.

Speed isn’t the only new thing in beta 7 though, according to Mozilla they’ve made a few other improvements; the full Bug and Fix list can be found here.

Uses JägerMonkey, a new, faster JavaScript engine

WebGL is enabled by default on Windows and Mac OS X. WebGL support requires an OpenGL-capable graphics card. Support for other graphics cards on Windows (specifically Intel GPUs) and Linux will be coming in a future beta

Certain rendering operations are now hardware-accelerated using Direct3D 9 on Windows XP, Direct3D 10 on Windows Vista and 7, and OpenGL on Mac OS X

Improved web typography using OpenType with support for ligatures, kerning and font variants

HTML5 Forms API makes web-based forms easier to implement and validate

What about looks?

Have you seen the new interface for Firefox 4 beta?  It looks a lot like IE9, except done correctly.  They’ve minimized the amount of space used up by the toolbars, and done away with the status bar at the bottom entirely.  They made a smart move by moving the bookmarks menu to a single Star button, it’s simple and small, but it’s there if you need it.  At one point I was in love with the minimalism of Chrome, but this latest version of Firefox does a great job.

    how do u interpret the sunspider benchmark numbers..?

    • goLfie December 17, 2010 at 7:04 am #

      The Sunspider benchmarks are measured in milliseconds and includes tests to generate a tagcloud from JSON input, a 3D raytracer, cryptography tests, code decompression, and many more examples. There are a few microbenchmarkish things, but they mostly represent real performance problems that developers have encountered.

      In other words it measures how long it takes the browser to render commonly used javascript language.

        first thanks for the reply and if i’m understanding this correctly then ie8 is the that correct? sorry but i suffer from newbie-itus.

          yeah IE8 is slower than molasses. Since we’re talking about the amount of time it takes to render something, low number = good thing.

    Does the Firefox 4 Beta accept Norton Identity Safe? I have always refrained from updating until I know that I can still use Norton to access my secure sites.

      Disregard my post. I failed to look at the date of the original post. I will survive the embarrassment.
