WebM for IE9 is a Google-developed application designed to enable WebM video playback in Internet Explorer 9. By default, IE9 does not support WebM videos, making this add-on essential for viewing such content seamlessly. WebM is a highly promising video format, gaining popularity for its efficiency and quality. With WebM for IE9, you can enjoy WebM videos directly in your browser without any hassle. It's important to note that if you are using Firefox, Chrome, or Opera, you won't need this add-on as these browsers natively support WebM. Enhance your IE9 experience with WebM for IE9 and stay prepared for the future of video streaming.

I had a somewhat decent experience with WebM for IE9. It plays videos, but occasionally it freezes. I appreciate the effort put into it, though – hoping for future updates to fix these kinks!
