Firefox 9 now available for download, offers 30% JavaScript performance boost

Wednesday, December 21st, 2011

Mozilla released Firefox 9 on Tuesday, the latest version of its popular web browser. Firefox 9 adds several enhancements, but perhaps the most notable is its improved JavaScript engine that reportedly offers up to a 30% performance boost (in Kraken and V8 benchmarks) on Javascript-heavy sites. The browser also adds OS X Lion optimizations that should improve two-finger swipe navigation and theme support. Other features include support for font-stretch, improved support for text-overflow, improved support for HTML5, MathML and CSS, and stability fixes. Firefox 9 is available for free now and builds are available for Mac, Linux and Windows.

Internet Explorer 9 racks up 2.35M downloads in 24 hours [video]

Thursday, March 17th, 2011

Via a recent blog post, Microsoft let it be known that its freshly released Internet Explorer 9 web browser has been downloaded more than 2.35 million times during its first 24 hours on the market. Released on Monday evening, the update brings hardware accelerated graphics, a new JavaScript engine, an updated user interface, and a host of other improvements. As a point of comparison, Mozilla’s FireFox 3 was downloaded more than 8 million times in its inaugural 24 hours back in June of 2008 — although it was trying to break into the Guinness Book of World Records. Regardless, it is quite the accomplishment, and something the folks from Redmond should be very proud of. If you haven’t been prompted by Windows Update yet, Internet Explorer 9 can be downloaded here.

Apple calls foul on web browser speed test

Thursday, March 17th, 2011

Earlier today, we told you about a study conducted by Blaze Software comparing the native browser speeds in Apple’s iOS and Google’s Android. The results of over 45,000 tests were published, and the firm concluded that Android was roughly 52% faster than iOS in terms of browser performance. Not so fast, says Apple. In a statement to blog The Loop, an Apple spokesperson pointed out a perceived flaw in Blaze Software’s methodology. “Their testing is flawed because they didn’t actually test the Safari web browser on the iPhone,” wrote Apple’s spokesperson. “Instead they only tested their own proprietary app which uses an embedded web viewer that doesn’t take advantage of Safari’s web performance optimizations. Despite this fundamental testing flaw, they still only found an average of a second difference in loading web pages.” The UIWebView framework, which was used to run Blaze’s “proprietary app” in an “embedded web viewer,” does not leverage Apple’s Nitro JavaScript engine — the part of mobile Safari that Apple claims is nearly 2x faster than its predecessor. Tests that leverage the enhanced JavaScript engine would, according to Apple, have improved Safari’s performance. Blaze Software has yet to publicly comment on Apple’s rebuttal.

Developers: Apple throttling Web app speeds on iPhone homescreen

Tuesday, March 15th, 2011

According to reports from developers speaking to The Register, iOS web applications — when launched from the home screen of an iPhone or iPad — run 2 to 2.5 times slower than if launched directly from the Safari web browser. Right now it’s unclear if Apple is directly, or indirectly, causing this to happen. It’s possible that the speed cut is a result of a bug, but the developers have pointed out that it makes web apps less desirable than those that can be downloaded or purchased through the iTunes App Store. If Apple is doing this on purpose, it could be viewed as an attempt to force developers to publish content to the company’s mobile application store — where Apple takes a 30% cut of sales revenues. “Apple is basically using subtle defects to make web apps appear to be low quality—even when they claim HTML5 is a fully supported platform,” argued one developer. Another developer said that Apple is using an older JavaScript engine, which is causing some of the issues. Web sites that are saved to the homescreen as web apps cannot take advantage of HTML5′s application caching capabilities, which allows for offline viewing. Developers have filed bug reports with Apple, but have yet to receive any feedback.

MIX10 is going strong and this year, the Microsoft conference has been filled with big announcements. Yesterday, we learned about Windows Phone 7 Series development and today, we get a glimpse of what is coming in Internet Explorer 9. The latest web browser from Microsoft stays competitive by supporting several HTML 5 specifications including CSS3, Scalable Vector Graphics (SVG), XHTML parsing, and both embedded H.264/MPEG4 video and MP3/AAC audio. Microsoft’s latest web browser also includes a new and improved JavaScript engine that combined with its GPU-accelerated graphics promises to deliver a rich browsing experience. You can test drive the latest browser via an online demo over at Microsoft’s new IE9 website or, if you enjoy living life on the edge of a system collapse, you can download and install the Internet Explorer 9 platform preview.
