Sure, technology decisions often are the result of personal predilection, political scheming, and inter-company rivalries. But cold hard data still can win the day -- and that's the main reason why Mozilla is reconsidering its earlier decision not to support Google's WebP image format.

Specifically, new data shows that Google isn't just blowing smoke when it promised that using WebP lets Web site operators save precious bytes when it's sending Web-page data to browsers. Smaller file sizes mean that browsers can show Web pages faster, that Web site operators cut bandwidth usage, and that people with … Read more

Mozilla's Web site log-in alternative known as Persona unveiled a Beta 2 version today. Now you can sign in to any Web site supporting Persona using a Yahoo Mail account.

Persona, which is still in development, is an open authentication system that works on desktops and mobile devices. In addition to being able to log in using either your Persona ID or your Yahoo credentials, today's release introduces support for Firefox OS, which means you can expect to use Persona to log in to any Firefox OS devices that launch later this year. It also includes back-end changes … Read more

Mozilla is taking a new look at the WebP image format it once rejected after some large Web sites encouraged the Firefox developer to take a fresh look and after Google released a freshly upgraded version.

WebP, which derived from the VP8 video compression technology in the WebM project Google launched three years ago, is part of the search giant's effort to speed up the Web. In WebP's case, that speedup comes through use of an image compression technology Google says produces more compact files than either JPEG or PNG.

WebP can be used where both JPEG and … Read more

Higher-end video producers anxious to adapt to the new realities of online video will be pleased to know that Sorenson Squeeze 9 (Windows trial; Mac trial), released today, is trying to ease development of streaming-media Web sites.

Web video is a flagship feature of the newer HTML5 incarnation of Hypertext Markup Language. Adding the support is intended to make video as easy to use on Web pages as JPEG is for images. But it's not always so simple to use in the real world, so Squeeze 9 now generates video files and accompanying code quickly so Web developers can … Read more

CSS Variables, a handy technology to ease Web page programming, could be one casualty in Safari with Google moving its resources to its browser engine, Blink.

Google engineers wanted to "fork" the WebKit browser engine project that underlies both Safari and Chrome so they could accelerate the pace of Chrome development and adopt changes too extensive to fit into a single open-source project. Even though splitting Blink away from WebKit may make each browser engine more nimble, it also means it's harder to cooperate.

That's because common features must be developed and maintained by duplicate teams … Read more

The war on Windows 8 continued this week. But there's probably something more to that than an unpopular operating system.

The week began with Dell -- ostensibly one of the biggest proponents of Window 8 -- making bleak predictions about the OS in an SEC filing.

Dell didn't stop there. It had a damning statement about the PC too. "The deteriorating outlook for the PC market [is] a result of, among other things, smartphones and tablets cannibalizing PC sales."

Which brings us to the market-devouring iPad, which, since its release this week, has passed the three-year mark. … Read more

The WebKit browser engine is becoming a less flexible foundation for open-source projects with the departure of Google from the project this week and Apple's consequent paring back of the project.

WebKit is a broad project that includes participation from many interested parties -- not just Apple and Google, but also BlackBerry, Samsung, Amazon, Oracle, Adobe Systems, and the programmers involved with the KDE and Gnome user interfaces for Linux. Indeed, the open-source project began as KDE's KHTML engine for the Konqueror browser before Apple got involved.

Google's Chrome team left WebKit this week, forking the open-source … Read more

Firefox has readied a more nuanced approach to how it implements the controversial "Do Not Track" setting and the Android version of the browser has a new font face in the browser's latest betas.

Firefox 21 Beta (download for Windows, Mac, and Linux) introduces more user choice for the Do Not Track header. The header, first introduced two years ago in Firefox 4, sends a signal to Web sites to not track where people who have activated it go as they bop around the Web.

Up until now, implementations of it have been limited to "On" or "Off.&… Read more

The latest update to Chrome beta refocuses its attention on speed through better memory management, as well as making numerous HTML5 and offline improvements in today's release.

Google reports that Web site content loaded in Chrome 27 beta for Windows, Mac, and Linux, should appear about 5 percent faster because of how the browser manages its resources. Basically, the browser's resource scheduler gives more priority to critical resources, over preloaded content.

Calendar forms should look a bit cleaner in the beta because it now uses HTML5 date and time < input > code. WebReal-Time Communication (WebRTC) also gets … Read more
