        We have an update from WebKit team

        Unfortunately the CoreMedia feature WebKit uses to add WebM support is disabled unless the framework is signed with an entitlement we can't use in open source builds.

        It is not clear why is Apple not allowing WebM for open source WebKit. Please feel free to post for clarification in WebKit.

            laiz Not for me on the Mojave version of 0.99.126.4.1.3-rc it seems:

            Sorry. Your browser reports that it cannot play WebM Video. The browser responded with:

            • canPlayType supported? No
            • WebM video supported? N/A

                orionuser6651 webm support is handled on the macOS level, so Orion will support it where available
