firefox57+打开streams后部分视频无法播放

[jiayiming]

dom.streams.enabled和javascript.options.streams改为true后不少视频用最高清晰度会报错 比如http://v.youku.com/v_show/id_XMzg1NDkwNDE1Ng==.html

播放错误 { "url": "http://v.youku.com/v_show/id_XMzg1NDkwNDE1Ng==.html?spm=a2h1n.8261147.reload_201810.1~3~DL~DT~A&s=efbfbd1ac6bdefbfbd77", "playing_quality": "mp4sd", "type": "NetworkError", "info": "Exception", "detail": { "code": -1, "msg": "NetworkError when attempting to fetch resource." } }
