이것이 버그로 간주되는지 확실하지는 않지만, Firefox에서 임베드된 YouTube 영상에 더 이상 썸네일이 표시되지 않습니다.

확인했습니다. 이는 새로운 회귀 버그입니다. @techAPJ 오늘 확인해 주시겠습니까?

[이 커밋](https://github.com/discourse/discourse/commit/4c3a01f58df6e4f4b21671ae7d756f639fa6205a)을 통해 수정되었습니다 (빌드 오류를 수정하기 위한 [후속 커밋](https://github.com/discourse/discourse/commit/ec84b00aff7fd9a7d6607cb21fd4745bb4aac5e3) 포함).

Firefox가 CSS에서 프로토콜 상대 URL(`//img.youtube.com`)을 더 이상 지원하지 않는 것 같습니다. 이를 해결하기 위해 [Stack Overflow의 이 답변](https://stackoverflow.com/a/28454204)에 따라 기본적으로 `https://img.youtube.com` URL을 사용하도록 변경했습니다.

이 문제를 보고해 주셔서 감사합니다 @smrtey 👍
