如果您想阻止用户在Firefox浏览器中更改^(Firefox)相机、位置和麦克风首选项^{(Camera, Location and Microphone preferences)}，您可以这样做。尽管任何用户都可以允许或阻止特定网站使用摄像头、位置和麦克风，但您可以使用GPEDIT和REGEDIT禁用该权限更改首选项。

某些网站需要您的相机或麦克风才能完成特定任务。但是，如果其他用户一直更改这些设置，使您难以保留所有个性化偏好，您可以阻止他们更改这些选项。

阻止用户在Firefox中更改^(Firefox)相机^(Camera)、位置^(Location)、麦克风^(Microphone)首选项

要防止用户使用组策略编辑器更改^{(Group Policy Editor)}Firefox中的^(Firefox)Camera、Location、Microphone首选项，请执行以下步骤 -

1. 按Win+R打开运行提示。
2. 输入gpedit.msc并点击Enter按钮。
3. 导航到计算机配置中的^{(Computer Configuration)}相机^{( Camera)}。
4. 双击不允许更改首选项^{(Do not allow preference to be changed)}设置。
5. 选择启用^(Enabled)选项。

这些步骤可让您阻止其他人更改Firefox浏览器中的^(Firefox)相机^(Camera)相关设置。但是，如果您想阻止他们更改麦克风^(Microphone)或位置^(Location)设置，您需要打开 麦克风 ^{(Microphone )}和 位置 ^(Location )文件夹并找到相同的 不允许更改首选项^{(Do not allow preference to be changed)} 设置。接下来，选择 Enabled 选项并分别单击 OK 按钮。

阻止用户在^(Block)Firefox中更改相机^(Camera)、位置^(Location)、麦克风^(Microphone)首选项

之后，按照所有步骤创建密钥。右键单击 Policies > New > Key，并将其命名为 Mozilla。

现在，右键单击 Mozilla > New > Key，并将其命名为 Firefox。接下来，右键单击 Firefox > New > Key，并将其命名为 Permissions。之后，右键单击 Permissions > New > Key，并将其命名为 Camera。

创建 Camera 键后，右键单击它，选择 New > DWORD (32-bit) Value，并将其命名为 Locked。

双击此REG_DWORD值并将值^(Value)数据设置为 1。

单击 确定 ^(OK )按钮以保存更改。

如果您想阻止用户更改麦克风^(Microphone)或位置^(Location)设置， 请在 权限 键中创建^{(Permissions )}麦克风 ^{(Microphone )}和 位置子^{(Location sub-)}键。然后，您可以 按照上述相同步骤创建Locked REG_DWORD值。^(REG_DWORD)

Stop users from changing Camera or Microphone preferences in Firefox

If you want to рrevent users from changing Camera, Location and Microphone preferences in the Firefox browser, here is how you can do that. Although any user can allow or block a particular website from using the camera, location, and microphone, you can disable that permission-changing preference using GPEDIT and REGEDIT.

Some websites require your camera or microphone to complete a particular task. However, if other users change those settings all the time, making it difficult for you to retain all the personalization preferences, you can block them from changing those options.

Prevent users from changing Camera, Location, Microphone preferences in Firefox

To prevent users from changing Camera, Location, Microphone preferences in Firefox using the Group Policy Editor, follow these steps-

1. Press Win+R to open the Run prompt.
2. Type gpedit.msc and hit the Enter button.
3. Navigate to Camera in Computer Configuration.
4. Double-click on Do not allow preference to be changed setting.
5. Select the Enabled option.
6. Click the OK button.
7. Do the same with Location and Microphone settings.

It is required to integrate the Firefox template in Group Policy on your Windows 10 computer.

At first, you have to open the Local Group Policy Editor. For that, press Win+R, type gpedit.msc, and hit the Enter button. Once it is opened, navigate to the following path-

Computer Configuration > Administrative Templates > Mozilla > Firefox > Permissions > Camera

Here you can see a setting called Do not allow preferences to be changed. Double-click on this setting and select the Enabled option.

Click the OK button to save the change.

These steps let you stop others from changing the Camera related settings in the Firefox browser. However, if you want to prevent them from changing the Microphone or Location settings, you need to open the Microphone and Location folder and find out the same Do not allow preference to be changed setting. Next, choose the Enabled option and click the OK button, respectively.

Block users from changing Camera, Location, Microphone preferences in Firefox

To block users from changing Camera, Location, Microphone preferences in Firefox using the Registry Editor, follow these steps-

1. Press Win+R to open the Run prompt.
2. Type regedit and hit the Enter button.
3. Click the Yes button.
4. Navigate to Policies in HKEY_LOCAL_MACHINE.
5. Right-click on Policies > New > Key.
6. Name it as Mozilla.
7. Right-click on Mozilla > New > Key.
8. Name it Firefox.
9. Right-click on Firefox > New > Key.
10. Name it as Permissions.
11. Right-click on Permissions > New > Key.
12. Name it as Camera.
13. Right-click on Camera > New > DWORD (32-bit) Value.
14. Name it as Locked.
15. Double-click on it to set the Value data as 1.
16. Click the OK button.
17. Create Location and Microphone keys to make the change for them.

Let’s check out these steps in detail.

At first, press Win+R, type regedit, hit the Enter button, and click the Yes option to open Registry Editor on your computer. Once it is opened, navigate to the following path-

HKEY_LOCAL_MACHINE\SOFTWARE\Policies

After that, follow all the steps minutely to create keys. Right-click on Policies > New > Key, and name it as Mozilla.

Now, right-click on Mozilla > New > Key, and name it as Firefox. Next, right-click on Firefox > New > Key, and name it as Permissions. After that, right-click on Permissions > New > Key, and name it as Camera.

Once the Camera key is created, right-click on it, select New > DWORD (32-bit) Value, and name it as Locked.

Double-click on this REG_DWORD value and set the Value data as 1.

Click the OK button to save the change.

If you want to prevent users from changing the Microphone or Location settings, create Microphone and Location sub-key in the Permissions key. Then, you can create the Locked REG_DWORD value by following the same steps as mentioned above.

That’s all!
