如果Firefox^{(Firefox opens automatically)}在您的Windows计算机打开时自动打开，那么这篇文章将展示如何阻止Firefox在启动时打开，它通常发生在几种情况下。可能是计算机突然关闭，或者您可能已将其设置为在您使用帐户登录后立即自动打开它。

阻止 Firefox^{(Stop Firefox)}在启动时打开

在我们继续禁用某些功能之前，您应该知道有时它很有帮助。这种重新启动还会重新打开您之前正在处理的先前打开的选项卡。在开始之前，请检查Windows 10 是否设置为在重新启动后打开程序^{(Windows 10 is set to open programs after a restart)}。

1]禁用Firefox应用程序重新启动^{(1] Disable Firefox Application Restart)}

• 打开 Firefox，然后在新选项卡的地址栏中键入about:config。按 Enter^{(Hit Enter)}。
• 您将收到一条通知，上面写着“This might void your warranty!” 可能会出现警告页面。
• 单击^(Click) 我接受风险，继续到 about:config 页面。
• 在搜索栏中，键入 toolkit.winRegisterApplicationRestart 并双击它以将其值设置为 false。

更改立即生效。

无需重新启动Firefox。它将确保阻止Firefox自动启动。

2]从Windows启动中删除Firefox^{(2] Remove Firefox from Windows Startup)}

很多时候，我们将程序设置为在我们自动登录到Windows后立即启动。虽然它确实增加了启动时间，但它对许多人很有用。但是，如果您没有这样做，以下是如何从Windows Startup中删除^{(Windows Startup)}Firefox。

• 右键单击^{(Right-click)}任务栏，然后单击任务管理器^{(Task Manager)}。
• 切换到Start-up，然后找到Firefox。
• 右键单击它并选择禁用。

您还可以使用启动管理器应用程序^{(use a Startup Manager app)}来阻止应用程序在启动时打开。

3]通过组策略从启动中删除Firefox^{(3] Remove Firefox from Startup via Group Policy)}

• 在运行提示中键入gpedit.msc ，然后按 Enter。^(gpedit.msc)
• 它将打开组策略编辑器^{(Group Policy Editor)}。
• 导航^(Navigate)到User Configuration > Adminstrative Templates > System > Logon。
• 检查Firefox是否是可以从^(Firefox)Windows Logon启动的程序列表的一部分。
• 如果是，请将其删除。
• 保存并退出。

从Windows 启动^{(Windows Startup)}中删除程序相对容易，但请确保您了解您可能会丢失^{(might lose tabs)}您正在使用的选项卡。

How to stop Firefox from opening on startup in Windows 10

If Firefox opens automatically when your Windows computer turns on then this post shows how to stop Firefox from opening on startup, it usually happens in a couple of scenarios. It’s possible that there was an abrupt shutdown of the computer or you may have set it to open it automatically as soon as you log in with your account.

Stop Firefox from opening on startup

Before we go ahead and disable some features, you should know that sometimes it’s helpful. This kind of restart also reopens the previously opened tabs which you were working on earlier. Before you begin, do check if Windows 10 is set to open programs after a restart.

1] Disable Firefox Application Restart

• Open Firefox, and type about:config in the address bar of the new tab. Hit Enter.
• You will receive a notice which says “This might void your warranty!” warning page may appear.
• Click I accept the risk, to continue to the about:config page.
• In the search bar, type toolkit.winRegisterApplicationRestart and double-click on it to set its value to false.

The changes apply immediately.

There is no need to restart Firefox. It will make sure to prevent Firefox from starting automatically.

2] Remove Firefox from Windows Startup

Many a time we set programs to launch as soon as we login to Windows automatically. While it does increase the startup time, but its useful for many. However, if you did not do it, here is how you can remove Firefox from Windows Startup.

• Right-click on the taskbar, and click on the Task Manager.
• Switch to Start-up, and find Firefox.
• Right-click on it and select disable.

You may also use a Startup Manager app to stop apps from opening at startup.

3] Remove Firefox from Startup via Group Policy

• Type gpedit.msc in the run prompt, and hit enter.
• It will open the Group Policy Editor.
• Navigate to User Configuration > Adminstrative Templates > System > Logon.
• Check if Firefox is part of the list of programs which can start with Windows Logon.
• If yes, remove it.
• Save and Exit.

It’s relatively easy to remove programs from Windows Startup, but make sure you understand that you might lose tabs with which you were working.
