Firefox 4 Pre-release gets WebM (VP8) support

Mozilla developers have pushed WebM, VP8 codec into Firefox 4, the next major Firefox update. Up till now Google’s open source VP8 codec was present only in a special Firefox development build that you can still download here at Firefox WebM Builds.

To test Firefox 4 pre-release with in-built WebM, download it here and follow instructions on how to play WebM powered YouTube video clips. Firefox 4 nightly builds are available for Mac, Linux and Windows operating systems. Windows users are advised to download Firefox-3.7a5pre standalone, no-install (the zipped pack) that doesn’t compromise your stable 3.6.x.

Google recently rejiggered the license on its open-source VP8 video codec after complaints that it wasn’t really “open”.
