WebM in Firefox

The new open-source video codec appeared in a developer version of the browser
So far everyone was in agreement (except Apple) about Webm, the new codec from the open-source Google VP8. But the question of license (see elsewhere) had caused some problems for the beginning of its implementation in browsers.
These problems are now resolved and keeps his word and Mozilla Firefox integrating Webm 4.To be more precise, Mozilla includes support for this codec in a fairly unstable pre-release that can be found on the "nightly-builds", the ftp the latest development versions being updated daily by the foundation.

"If you are looking for videos Webm test, you can watch on YouTube Webm HTML5 experiement with the nightly builds, advises Chris Pearce, developers at Mozilla.There is still a little early to compare the performance videos of this version with those of Chrome (which he is also a version for developers) but is not essential.The important thing in this announcement is that the motion for adoption is indeed well underway.

Apple's side continues to support the H.264 and has not yet officially announced his intentions on Webm.
