Pode ser uma limitação/exigência do próprio site.
Acontece-me o mesmo, mas só no facebook! Dá uns 10, 15 segundos e pára. A única solução é fazer refresh ou então abrir o vídeo directamente do site. Já desactivei o uBlock mas o problema mantém-se. Estou a ver que vou ter de mudar de browser, embora me pareça que o bug esteja relacionado com o FB.Por vezes a imagem dos vídeos param no youtube.
