Summary
Firefox 148 adds support for the Document Picture-in-Picture API: see https://bugzilla.mozilla.org/show_bug.cgi?id=1858562.
We support all features except for the
DocumentPictureInPicture/requestWindow()disallowReturnToOpeneroption; see https://bugzilla.mozilla.org/show_bug.cgi?id=1858562#c21.The feature is available by default in Nightly only. In non-Nightly 148+ Firefox, you can enable it via the
dom.documentpip.enabledpref. I wasn't sure if I should include the pref information in the BCD, or just include it in the Experimental features writeup...?Test results and supporting details
