你^(Are)是火狐^(Firefox)用户吗？如果是，您可能遇到过浏览器突然冻结或挂起并意外关闭或崩溃到无响应模式的情况。

冻结或挂起^(Hanging)是程序停止响应用户输入的过程。挂起或冻结与崩溃^(crash)不同。崩溃^(Crash)结束程序，并且窗口自动关闭。原因可能很多。它可能包括在插件中安装不兼容的主题、扩展或编程错误。我建议您执行一些故障排除步骤，以防您发现Firefox在^(Firefox)Windows中给您带来问题。

Firefox^{(Firefox Freezes)}在Windows 11/10上冻结、挂起^(Hangs)或无响应^{(Unresponsive)}

1]清除Firefox浏览器缓存^{(Firefox Browser Cache)}，历史^(History)和下载历史^{(Download History)}

随着下载历史的积累，文件需要更长的时间来下载。要修复此冻结，请单击“下载^(Downloads)”图标或按Ctrl+J。，转到Firefox菜单，然后单击“下载”^{( ‘Downloads’)}并单击“清除下载”^{(‘Clear Downloads’)}以清除下载历史列表^{(Download History List)}。

此外，如果Firefox试图保存文件的文件夹不可访问，它可能会冻结。

尝试在about:config^{(about:config)}中重置browser.download.lastDir首选项。您也可以尝试在Firefox设置中更改下载文件夹位置。打开^{(changing the Download folder location)}设置^(Settings)>Options > General选项卡。在这里，在下载^(Downloads)下浏览到桌面^(Desktop)或所需的文件夹并选择它。

有时浏览历史^(History)会干扰浏览器启动，因此可能会无限期挂起Firefox。

清除历史记录^(History)以避免这种情况。在此处打开Firefox Options > Privacy和安全^(Security)并清除历史记录^(History)等。

您还可以考虑使用CCleaner来清理整个Firefox Cache等。

2] 坏 Firefox 附加组件

我的下一个建议是让您将Firefox 打开到安全模式^{(open Firefox to Safe Mode)}并检查您是否安装了任何错误的附加组件。如果在您键入内容或单击按钮链接时Firefox浏览器在没有任何警告的情况下冻结，请关闭所有选项卡并以安全^(Safe)模式启动Firefox 。

为此，请打开Firefox浏览器，单击右上角的设置^(Settings)按钮。接下来单击蓝色的小圆形问号标志。接下来，选择Restart with Add-ons disabled。

 现在，如果Firefox在没有冻结的情况下运行，则表明插件有问题——无论是扩展程序还是工具栏——一些扩展程序容易出现内存泄漏^{(memory leaks)}。

接下来，打开Firefox 菜单^{(Firefox Menu)}并选择附加组件^(Add-ons)（或按Ctrl+Shift+A）。您可以在此处禁用或管理 Firefox 附加组件^{(manage Firefox add-ons)}。一个接一个地禁用，并试图找出罪魁祸首。如果您可以识别有问题的加载项或扩展程序或工具栏，请将其卸载。

3]更新Adobe Flash版本

• 如果您在启动Firefox^(Firefox)时遇到冻结或延迟，您可能需要检查您的Adob​​e Flash、Java插件是否是最新的。某些版本确实会导致Firefox死机或崩溃。此页面^{(This page )}将告诉您安装了哪个版本的Adob​​e Flash。
• 如需更多信息，请访问Adob​​e Flash Player 下载中心^{(Adobe Flash Player Download Center)}。

4]检查Windows shell扩展

某些Windows shell 扩展也可能导致Firefox浏览器出现问题，导致其冻结或崩溃。您可以使用ShellExView查看所有资源管理器外壳扩展，然后尝试有选择地禁用您怀疑可能导致问题的扩展。

5] 第三方软件的扩展

您的防病毒、安全套件、站点顾问、密码管理器、下载管理器的扩展也可能是一个可能的原因。再次^(Again)，有选择地禁用每一个，看看您是否可以识别出问题的问题。

6]创建一个新的配置文件

Firefox 用户配置文件管理器^{(Firefox User Profile Manager)}允许您创建附加配置文件。在Firefox^(Firefox)中创建一个新配置文件并将所有设置和其他数据传输到新配置文件，看看它是否有帮助。

7]减少Firefox内存使用

您可能还需要考虑通过更改about:config 首选项来减少^{(about:config preferences)}Firefox的内存使用量。您可能特别想调整这些设置：

• browser.cache.memory.capacity,
• browser.cache.memory.enable
• browser.sessionhistory.max_total_viewers 设置。

仅当您知道自己在做什么时才这样做。通过执行调整、删除主题、角色^(Personas)和减少附加组件或插件来减少内存使用也可以帮助您解决问题。

如果没有，您可能需要Refresh Firefox。您还可以在线调整和刷新 Mozilla Firefox 浏览器。

Firefox Freezes, Hangs or Unresponsive on Windows 11/10 computer

Αre you a Firefox user? If yes, you might have comе across an instance where the browser suddenly freezes оr hangs and closes down unexpectedly or collapses into a not responding mode.

Freezing or Hanging is a process where a program stops responding to a user’s input. A hang or a freeze is different from a crash. A Crash ends the program, and the windows automatically shut down. The reasons can be many. It could include the installation of incompatible themes, extensions, or programming errors in plugins. I am suggesting some troubleshooting steps which you could follow in case you find that your Firefox is giving you problems in Windows.

Firefox Freezes, Hangs or Unresponsive on Windows 11/10

1] Clear Firefox Browser Cache, History & Download History

Files take longer to download as the download history builds up. To fix up this freeze, click on the Downloads icon or press Ctrl+J. , go to the Firefox menu, then ‘Downloads’ and click on ‘Clear Downloads’ to clear the Download History List.

Also, if the folder where Firefox is attempting to save the file is not accessible, it can freeze.

Try resetting the browser.download.lastDir preference in about:config. You can also try changing the Download folder location in your Firefox settings.Open Settings > Options > General tab. Here, under Downloads browse to the Desktop or the desired folder and select it.

At times Browsing History interferes with the browser start-up and therefore can hang Firefox for indefinite periods.

Clear the History to avoid this instance. Open Firefox Options > Privacy & Security and clear the History, etc., here.

You could also consider using CCleaner to clear up your entire Firefox Cache, etc.

2] Bad Firefox Add-on

My next suggestion would be for you to open Firefox to Safe Mode and check out if you have any bad add-ons installed. If the Firefox browser freezes without any warning when you type something or click on a button link, close all the tabs and start Firefox in Safe mode.

To do this, open the Firefox browser, click on the Settings button in the top right corner. Next click on the small blue circular question mark sign. Next, select Restart with Add-ons disabled.

 Now, if Firefox runs without freezing, it suggests a bad add-on – either an extension or toolbar – some extensions are prone to memory leaks.

Next, open Firefox Menu and select Add-ons (Or press Ctrl+Shift+A). Here you can disable or manage Firefox add-ons. Disable each one, one after the other, and try to find out the culprit. If you can identify the offending add-on or extension or toolbar, uninstall it.

3] Update Adobe Flash version

• If you are facing freezing or experiencing a  delay while starting Firefox, you might want to check out if your Adobe Flash, Java plugins are up-to-date. Some versions did cause Firefox to freeze or crash. This page will tell you which version of Adobe Flash, you have installed.
• For more info, visit Adobe Flash Player Download Center.

4] Check Windows shell extensions

Some Windows shell extensions can also cause problems with your Firefox browser, causing it to freeze or crash. You can use ShellExView to see all the explorer shell extensions and then try to selectively disable extensions which you suspect could be the cause of your problems.

5] Extensions of 3rd party software

Extensions of your antivirus, security suite, site advisors, password manager, download managers could also be a possible cause. Again, disable each one selectively and see if you can identify the offending issue.

6] Create a new Profile

The Firefox User Profile Manager allows you to create an additional profile. Create a new profile in Firefox and transfer all your settings and other data to the new profile, and see if it helps.

7] Reduce Firefox memory usage

You may also want to consider reducing memory usage of Firefox by changing the about:config preferences. You may especially want to tweak these settings:

• browser.cache.memory.capacity,
• browser.cache.memory.enable
• browser.sessionhistory.max_total_viewers settings.

Do so only if you know what you are doing. Reducing memory usage by carrying out just tweaks, removing themes, Personas, and reducing add-ons or plugins can also help you resolve your problem.

If it doesn’t, you may want to Refresh Firefox. You can also Tune-up and Refresh Mozilla Firefox browser online.
