Submission + - WebRTC Makes Firefox's Social API Even More Social (

theweatherelectric writes: Mozilla has put together a demo which combines WebRTC with Firefox's Social API. Over on Mozilla's Future Releases blog, Maire Reavy writes, 'WebRTC is a powerful new tool that enables web app developers to include real-time video calling and data sharing capabilities in their products. While many of us are excited about WebRTC because it will enable several cool gaming applications and improve the performance and availability of video conferencing apps, WebRTC is proving to be a great tool for social apps. Sometimes when you’re chatting with a friend, you just want to click on their name and see and talk with them in real-time. Imagine being able to do that without any glitches or hassles, and then while talking with them, easily share almost anything on your computer or device: vacation photos, memorable videos – or even just a link to a news story you thought they might be interested in – simply by dragging the item into your video chat window.'

Submission + - The Shumway Open SWF Runtime Project (

theweatherelectric writes: Mozilla is looking for contributors interested in working on Shumway. Mozilla's Jet Villegas writes, 'Shumway is an experimental web-native runtime implementation of the SWF file format. It is developed as a free and open source project sponsored by Mozilla Research. The project has two main goals: 1. Advance the open web platform to securely process rich media formats that were previously only available in closed and proprietary implementations. 2. Offer a runtime processor for SWF and other rich media formats on platforms for which runtime implementations are not available.'

Submission + - Tilt: Visualise Your Web Page in 3D (

theweatherelectric writes: Mozilla Hacks has an article on Tilt, a Firefox extension which visualises the DOM tree of a Web page in 3D. They write, 'Tilt is a Firefox extension that lets you visualize any web page DOM tree in 3D. It is being developed by Victor Porof (3D developer responsible with the Firefox extension itself), along with Cedric Vivier (creating a WebGL optimized equivalent to the privileged canvas.drawWindow, see #653656) and Rob Campbell (who first thought about creating a 3D visualization of a webpage). Everything started initially as a Google Summer of Code project, but now, with an enthusiastic team behind it and so many new features and ideas, it has become an active Developer Tools project.' There's also a Tilt blog for development updates.

Submission + - pdf.js Reaches First Milestone (

theweatherelectric writes: The pdf.js project aims to implement a PDF viewer using standards-compliant Web technologies. The project has reached its first milestone: it renders the sample PDF (a paper on Mozilla's Tracemonkey JavaScript engine) perfectly. However, that perfection currently comes with some caveats: 'pdf.js produces different results on pretty much every element in the browser×OS matrix. We said above that pdf.js renders the Tracemonkey paper “perfectly” if you’re running a Firefox nightly. On a Windows 7 machine where Firefox can use Direct2D and DirectWrite. If you ignore what appears to be a bug in DirectWrite’s font hinting. The paper is rendered less well on other platforms and in older Firefoxen, and even worse in other browsers. But such is life on the bleeding edge of the web platform.' Still, the progress so far has been impressive and pdf.js will no doubt get better with time.

Submission + - Advertisers and Publishers Adopt Do Not Track (

theweatherelectric writes: As noted by the Mozilla Blog, the AP News Registry is the first large scale service to support the Do Not Track (DNT) feature of Firefox 4 and Internet Explorer 9. They write, 'The Associated Press (AP) is the first company to deploy DNT on a large scale, and it only took a few hours for one engineer to implement. The AP News Registry tracks 1 billion impressions of news content, with 175 million unique visitors per month, and has membership with more than 800 sites. When consumers send a DNT preference via the browser while viewing a story at one of its publisher’s sites, the AP News Registry no longer sets any cookies. The previous solution was for users to opt-out via a link to a central opt-out page referenced in each participating news site’s privacy policy. They still count the total number of impressions for each news story, but aggregate consumer data for those with DNT in a non-identifiable way.'

Submission + - Investigating the Performance of Firefox 4 and IE9 (

theweatherelectric writes: Mozilla's Robert O'Callahan has posted an article on his blog in which he investigates the performance differences between Firefox 4 and IE9. He writes, 'As I explained in my last post, Microsoft's PR about "full hardware acceleration" is a myth. But it's true that some graphics benchmarks consistently report better scores for IE9 than for Firefox, so over the last few days I've been looking into that. Below I'll explain the details [of] what I've found about various commonly-cited benchmarks, but the summary is that the performance differences are explained by relatively small bugs in Firefox, bugs in IE9, and bugs in the benchmarks, not due to any major architectural issues in Firefox (as Microsoft would have you believe).'
