Which Broswer Supports Html5 Media Source Extensions

HTML Programming

When it comes to HTML5 media source extensions, it’s important to know which browsers support this feature. As a web developer, I’ve had my fair share of experiences working with different browsers and their compatibility with HTML5 media source extensions. In this article, I’ll dive deep into the details and share my personal insights on which browsers support this powerful HTML5 feature.

What are HTML5 Media Source Extensions?

HTML5 Media Source Extensions (MSE) is a W3C specification that allows JavaScript to generate media streams for playback in HTML5 video and audio elements. MSE provides a standardized way to dynamically change the media source and handle adaptive streaming, enabling developers to create more customized and interactive media experiences on the web.

Browser Support for HTML5 Media Source Extensions

While HTML5 Media Source Extensions is a powerful feature, it’s important to understand which browsers support it to ensure a seamless user experience across different platforms.

Let’s take a look at the major browsers and their support for HTML5 Media Source Extensions:

Google Chrome

Chrome has been a leading browser in terms of supporting HTML5 features, and Media Source Extensions is no exception. Since version 23, Chrome has provided support for MSE. This has made it a favorable choice for developers who want to leverage the power of HTML5 media streaming.

Mozilla Firefox

Firefox is another popular browser that has embraced HTML5 Media Source Extensions. Starting from version 25, Firefox added support for MSE, allowing developers to create rich multimedia experiences. I’ve personally found Firefox to provide a smooth playback experience with HTML5 media streams.

Microsoft Edge

Microsoft Edge, the default browser for Windows 10, also supports HTML5 Media Source Extensions. Since its initial release, Edge has included MSE support, enabling developers to take advantage of dynamic media source changes and adaptive streaming within their web applications.

Apple Safari

While Safari is known for its strong HTML5 support, HTML5 Media Source Extensions is an exception. As of my knowledge, Safari still lacks support for MSE. This can be a limitation for developers who rely heavily on MSE features in their multimedia-rich web applications.

Other Browsers

It’s worth mentioning that other browsers, such as Opera and Brave, also support HTML5 Media Source Extensions. These browsers have made efforts to keep up with the latest web standards and offer developers the tools they need for creating cutting-edge multimedia experiences.


HTML5 Media Source Extensions provides developers with the ability to create powerful and interactive media streams within HTML5 video and audio elements. While major browsers like Chrome, Firefox, and Microsoft Edge have embraced this feature, Safari still lags behind in providing support for MSE. As a web developer, it’s important to consider browser compatibility when implementing HTML5 Media Source Extensions to ensure a seamless experience across different platforms.
