Mozilla won’t implement WEI

They are going to fight against WEI. Tooth and nails, for our sakes!

Just like they did with EME, the closed source video DRM in 2014. By being deeply concerned with the direction the web is going, and definitely against it, but...

We face a choice between a feature our users want and the degree to which that feature can be built to embody user control and privacy.

With most competing browsers and the content industry embracing the W3C EME specification, Mozilla has little choice but to implement EME as well so our users can continue to access all content they want to enjoy.

Despite our dislike of DRM, we have come to believe Firefox needs to provide a mechanism for people to watch DRM-controlled content.

DRM requires closed systems to operate as currently required and is designed to remove user control, so Mozilla is taking steps to find alternative solutions to DRM. But Mozilla also believes that until an alternative system is in place, Firefox users should be able to choose whether to interact with DRM in order to watch streaming videos in the browser.
