Microsoft had released a similar plugin for Firefox earlier. Microsoft also said that IE9 would fully support third party WebM plugins. Users will just have to install a VP8 codec on their PC.WebM is an audio-video format designed to provide high-quality open video compression format for use with HTML5 video.
