Mozilla Releases Firefox 4 With Speed Enhancements and New Look


Mozilla today announced the official release of Firefox 4, the latest version of the organization's popular Internet browser, for Mac OS X, Windows, and Linux. With support for over 80 languages, Firefox 4 brings speed enhancements as well as a sleek new user interface, increased customizability, and new security and privacy features.

Firefox 4 is the fastest Firefox yet. With dramatic speed and performance advancements across the board, Firefox is between two and six times faster than previous releases. Major enhancements to the JavaScript engine make everything from startup time to page load speed to graphics and JavaScript performance screaming fast in Firefox.

The latest version of Firefox introduces a sleek new look that lets Web content take center stage. With features like App Tabs and Panorama, Firefox makes it easier and more efficient to navigate the Web. Firefox delivers industry-leading privacy and security features like Do Not Track and Content Security Policy to give users control over their personal data and protect them online.

Firefox 4.0 is of course a free download, with the Mac version requiring a minimum of Mac OS X 10.5 Leopard.

By their support of WebM, FireFox is dead to me.

How does the fact that FireFox supporting WebM impact you negatively in slightest?

What I assume you actually meant was: By them not supporting H264, FireFox is dead to me.. You can still play H264 encoded media via a Quicktime plug-in.

As FireFox is an open source project, Mozilla choose not to ship it with H264 due to it being a patent encumbered codec. People who should be worried about the fact that FireFox supports WebM are Apple. With both FireFox and Google's Chrome supporting WebM, it may become the de facto standard for web video, this would be bad for Apple as they have backed H264.
