我为我的 Firefox 创建了一个“用户配置”文件来提高安全性和性能，但我发现 YouTube 仅在到达当前缓冲内容的末尾时才会继续缓冲，这会导致整个视频出现严重中断，有人能告诉我哪个是错误的吗？
这是的开始pref.js：
# Mozilla User Preferences
/* Do not edit this file.
*
* If you make changes to this file while the application is running,
* the changes will be overwritten when the application exits.
*
* To make a manual change to preferences, you can visit the URL about:config

答案1
您需要的是一个用于禁用 dash 播放的脚本。 使用 YouTube 中心插件
然后，您应该会在 YouTube 主页上看到一个齿轮图标。单击该图标，然后在外部播放器下取消勾选 Dash 播放。 Dash 播放设置
Dash 播放的功能是在播放视频时对其进行缓冲。这可能会导致很多缓冲问题。
答案2
在地址栏中输入about:config~ 单击Accept。在搜索栏中输入mp4- 你会找到media.mediasource.mp4.enabled，将其设置为false。
这将解决 YouTube 视频问题。一些播放视频的网站需要启用它，因此需要true再次设置才能使这些视频正常工作。这是 Adobe Flash、HTML5 的东西。因此，创建一个文本文件夹，并使用我提供的信息将其设置在桌面上，这样如果您将来需要此信息，您就可以获得它。请记住，这about:config是 Firefox 浏览器的核心，所以除非您知道自己在做什么，否则不要更改其中的值，否则它会让 Firefox 不高兴。哈哈！希望这对您和所有人有所帮助！问候！
