* Bug 1724868 - news.yahoo.co.jp - Override UA on Android and Linux
* WebCompat issue #82605 - https://webcompat.com/issues/82605
*
* Yahoo Japan news doesn't allow playing video in Firefox on Android or Linux
* as those are not in their support matrix. They check UA override twice
* and display different UI with the same error. Changing the UA to Chrome via
* content script allows playing the videos.
