让 Firefox^{(Make Firefox)}在锁定屏幕^{(Lock Screen)}上显示媒体控制^{(Media Controls)}

Firefox浏览器已经为用户提供了许多播放媒体的选项，包括背景播放、画中画支持和自动播放设置。在Windows 10中显示锁定屏幕^{(Lock Screen)}上的媒体控件^{(Media Controls)}是另一种功能。要启用它，请按照以下说明进行操作。

1. 启动 Mozilla Firefox 浏览器。
2. 在地址栏中输入 about:config 并按Enter键。
3. 在搜索^(Search)过滤器框中键入媒体密钥
4. 搜索以下首选项 – media.hardwaremediakeys.enabled。
5. 双击media.hardwaremediakeys.enabled首选项并将其设置为 true。

尽管许多Firefox浏览器用户不知道此功能，但它是一个有用的附加功能，可让您直接从Windows 10 锁定屏幕^{(Lock Screen)}控制正在播放的媒体（音频或视频） 。

启动Firefox浏览器并打开一个新选项卡。

在地址栏中输入about:config并按^{(about: config)}Enter键。如果出现警告提示，请忽略它，然后继续进行。

接下来，在出现的新浏览器窗口中，在搜索框中键入^(Search)媒体^(Media)键以允许填充列表。

在列表中查找以下条目 – media.hardwaremediakeys.enabled。

默认情况下，首选项设置为False值意味着，媒体控制功能在^(False)Firefox中被禁用。要覆盖此更改，您需要将上述条目的值设置为True。

因此，双击 media.hardwaremediakeys.enabled 条目以将其值从False更改为True。

或者，您可以简单地切换偏好名称旁边的开关。

完成后，关闭窗口并退出。重新启动浏览器^{(Restart the browser)}以使更改生效。

这里的所有都是它的！希望^(Hope)有帮助！

Make Firefox display Media Controls on Windows 10 Lock Screen

Configuring Firefox to show the media controls over Lock Screen will let you pop media (audio or video+) out of their webpage into a floating, always on the top window so you can listen to your favorite music or audio and still continue to do other things. Read to know how to enable Firefox to display Media Controls over the Lock Screen in Windows 10.

Make Firefox display Media Controls on the Lock Screen

Firefox browser already gives users many options for playing media, including background playback, picture-in-picture support, and auto-play settings. Showing Media Controls over Lock Screen in Windows 10 adds as another capability. To enable it, follow the instructions given below.

1. Launch the Mozilla Firefox browser.
2. Type about: config in the address bar and hit the Enter key.
3. Type media keys in Search filter box
4. Search for the following preference – media.hardwaremediakeys.enabled.
5. Double-click on media.hardwaremediakeys.enabled preference and set it to true.

Although many Firefox browser users are not aware of this feature, it’s a useful addition that lets you directly control the playing media (audio or video) right from Windows 10 Lock Screen.

Launch the Firefox browser and open a new tab.

Type about: config in the address bar and hit the Enter key. If prompted by a warning, ignore it, and proceed further.

Next, in the new browser window that appears, type Media keys in the Search box to allow the list to populate.

Look for the following entry in the list – media.hardwaremediakeys.enabled.

By default, the preference is set to False value meaning, the media controls feature is disabled in Firefox. To override this change, you’ll need to set the value for the above entry to True.

So, double-click the media.hardwaremediakeys.enabled entry to change its value from False to True.

Alternatively, you can simply Toggle the switch, adjacent to the preference name.

Once done, close the window and exit. Restart the browser to allow the changes to take effect.

That’s all there is to it! Hope that helps!
