画中画模式^{(Picture-in-Picture mode)}是几乎所有现代网络浏览器中的一项重要功能，但如果您可以执行多个画中画呢？目前，这只能在单个网络浏览器中实现，那就是Mozilla Firefox。

如何在Firefox^(Firefox)中使用多个画中画模式

从我们收集到的信息来看，该功能运行良好。此功能的好处是用户能够打开多个视频并同时播放它们。不是大多数用户想要做的事情，但对于那些感兴趣的人，该选项随时可用。

1]在Firefox中^(Firefox)启动^(Launch)一个视频网站

您应该在这里做的第一件事是在Firefox^(Firefox)中启动一个与视频相关的网站，最好是YouTube，以进行此测试。从那里，找到您要播放的视频，然后单击它。

2]选择^(Select)画中画图标

将鼠标指针悬停在视频上，然后单击画中画图标继续前进。

这样做应该会激活该模式，因此视频会移动到网页的右侧。

3]重复上述步骤

如果您觉得需要运行多个画中画视频，您可以在同一网站上重复上述步骤，或打开一个包含不同视频的新标签。Firefox将一个接一个地播放它们，而不是同时播放它们。

4]关闭画中画模式

此功能可能不适合您；因此，如果您不想在每个视频上都看到图标，可以将其关闭。

通过单击浏览器右上角的Firefox菜单按钮来执行此操作，然后选择Options。

从那里向下滚动到浏览^(Browsing)并确保取消选中启用画中画视频控件^{( Enable picture-in-picture video controls)}。

Enable, disable or use multiple Picture-in-Picture video mode in Firefox

Picture-in-Picture mode is a crucial feature in almost all of the modern web browsers, but what if you could perform multiple picture-in-picture? At the moment, this is only possible in a single web browser, and that’s Mozilla Firefox.

How to use multiple Picture-in-Picture mode in Firefox

From what we’ve gathered, the feature works quite well. The good thing about this feature is the ability for users to open several videos and play them at the same time. Not something most users will want to do, but for those who are interested, the option is available at any time.

1] Launch a video website in Firefox

The first thing you should do here is to fire up a video-related website in Firefox, preferably YouTube, for this test. From there, locate a video you want to play, and click on it.

2] Select the picture-in-picture icon

Move on by hovering the mouse pointer over the video, then click on the picture-in-picture icon.

Doing this should activate the mode, and as such, the video moves to the right side of the webpage.

3] Repeat the steps above

If you feel the need to have multiple picture-in-picture videos running, you can repeat the steps above on the same website or open a new tab with a different video. Firefox will play them one after the other instead of all at the same time.

4] Turn off picture-in-picture mode

This feature might not be for you; therefore, you can turn it off if you do not wish to see the icon on every video.

Do this by clicking on the Firefox menu button at the top-right of the browser, then select Options.

From there, scroll down to Browsing and be sure to uncheck, Enable picture-in-picture video controls.
