monkeymonkey writes "Mozilla has integrated tracing optimization into SpiderMonkey, the JavaScript interpreter in Firefox. This improvement has boosted JavaScript performance by a factor of 20 to 40 in certain contexts. Ars Technica interviewed Mozilla CTO Brendan Eich (the original creator of JavaScript) and Mozilla's vice president of engineering, Mike Shaver. They say that tracing optimization will 'take JavaScript performance into the next tier' and 'get people thinking about JavaScript as a more general-purpose language.' The eventual goal is to make JavaScript run as fast as C code. Ars reports: 'Mozilla is leveraging an impressive new optimization technique to bring a big performance boost to the Firefox JavaScript engine. ...They aim to improve execution speed so that it is comparable to that of native code. This will redefine the boundaries of client-side performance and enable the development of a whole new generation of more computationally-intensive web applications.' Mozilla has also published a video that demonstrates the performance difference." An anonymous reader contributes links the blogs of Eich and Shaver, where they have some further benchmarks.

ruphus13 writes "Firefox has been pushing version 3.0 very aggressively, and firmly believes that it is a solid product. The Download Day was just one of their ways to drum up user support for the new release. Now, Firefox is going to 'gently nudge' users of Firefox 2.0 to upgrade. Some users may have been waiting for their add-ons to get upgraded, but now Mozilla is planning to apply a little nudge. Sometime within the next week, people using Firefox 2.0.0.16 will see a request to upgrade and though you'll have the option to decline, it's likely Firefox will ask again anyway. Users will most likely be offered a second chance to upgrade after several weeks. (Mozilla will stop supporting version 2 in December.) It will be interesting to see if this speeds up the rate of upgrade by users, as well as upgrades of the add-ons."

least_weasel writes "An article on Ars Technica reveals Mozilla's intention to create and release a plugin for Internet Explorer that would allow the often-criticized IE to utilize some of the cooler rendering code developed for Firefox. The current WIP focuses on rendering using HTML5 standards, but the plans seem to be more ambitious than just fixing this one small piece of IE. The article covers some of the plans, hurdles, and potential benefits. It also spills the beans on the code name for the project: Screaming Monkey."

An anonymous reader writes "Ogg Theora support for the HTML5 <video> tag is in the Firefox 3.1 nightlies. Theora is the only video format allowed on Wikimedia Commons, so Wikimedia people are pushing Wikipedia readers to download a nightly and try it out. Break it, crash it, report bugs, get it into good shape and nullify Apple and Nokia's FUD the best way possible. They may have gotten the words 'Vorbis' and 'Theora' removed from the HTML5 spec, but the market will tell them when their browsers are sucking."

Just as you were getting used to 3.0, those Mozilla guys have announced 3.1's Alpha release. FTA "Built on the pre-release version of the Gecko 1.9.1 platform, Shiretoko includes a variety of new features. Called an 'early developer milestone,' the release includes bug fixes, improved Web standards support, Text API for the Canvas Element, support for border images and JavaScript query selectors, and improvements to the tab-switching function and the Smart Location Bar." You can download it if you dare.

Barence writes in with a data point on Firefox 3 adoption: it's been available for 10 days, and already one site is seeing 55% of its Firefox-using visitors on version 3. "Microsoft still has three out of ten people running an old version of its browser more than 18 months after Internet Explorer 7 launched, while Firefox has converted more than half of its users to the latest version in just over a week. That should set a few alarm bells ringing in Redmond."

Joe Barr writes "Mayank Sharma has two recent stories on Linux.com; one evaluating the performance of Firefox 3, and the second comparing it to Opera 9.5. Which is better? For most people, it's probably more a matter of familiarity or personal preference, but these stories provide hard performance data to consider as well. Sharma notes, 'In terms of rendering JavaScript, Firefox 3 had the edge over Opera 9.5 in the SunSpider JavaScript Benchmark, which has an error range between +/-0.8% to +/-11.3% depending on the type of test. In the JavScript Engine speed test, Opera 9.5 scores over its peers when it comes to error handling, DOM, and AJAX.'" Slashdot shares a corporate overlord with Linux.com.

bunratty writes "Firefox 3 Beta 5 was released today. This last beta release sports performance-boosting improved connection parallelism. Not only has 'the memory leak' been fixed: Firefox now uses less memory than other browsers. This is not only according to Mozilla developers, but CyberNet and The Browser World as well. As for the Acid3 test, Firefox 3 Beta 5 scores only 71/100 compared to 75/100 for Safari 3.1 and 79/100 for the latest Opera 9.5 snapshot. The final release of Firefox 3 is expected in June."
