如果您的Mozilla Firefox浏览器在(Mozilla Firefox)Windows 11/10/8/7上经常崩溃，可能是在启动时，或者如果选项卡经常崩溃，那么在本指南中，我们将帮助您解决大多数Firefox崩溃问题。
Firefox在(Firefox)Windows 11/10 PC上不断崩溃
在本指南中，我们将介绍以下场景：
- Firefox 无法启动
- Firefox 在启动时不断崩溃
Firefox 无法启动
如果Firefox窗口未打开，或者您在尝试启动Firefox时收到错误消息，请按照以下方法进行修复。
没有错误信息：
- 重新启动计算机一次。
- 如果您的互联网安全软件包含“虚拟浏览”功能，请确保禁用该功能并清除虚拟缓存。
- 如果安装插件后它停止工作，那么您需要使用安全模式(use Safe Mode)。按住Shift 键(Shift-key)，然后双击Firefox快捷方式。
- 最后，尝试创建一个新的 Firefox 配置文件(a new Firefox Profile) ，然后启动它。
带有错误消息
1] Mozilla 崩溃报告器
如果您在启动Firefox后看到此窗口，请查看我们的指南 -诊断和修复 Firefox 问题的常用解决方案(Common solutions to diagnose and fix problems in Firefox)。
2] Firefox已经在运行但没有响应
如果Firefox 已经在运行但没有响应(Firefox is already running but is not responding)，那么问题是您在Firefox中的配置文件无法释放配置文件锁定(Profile Lock)。简而言之，如果一个进程对某些文件进行了锁定，那么其他人就无法使用它。每当应用程序关闭时，它就会停止访问它使用的文件。在我们的例子中，Firefox可能已经异常关闭，而将锁留在原地。
3]无法加载您的Firefox配置文件。(Firefox)它可能丢失或无法访问
当缓存(Cache)中的某些文件可能在您的配置文件中损坏或损坏时，就会发生这种情况。您可以通过删除profiles.ini 文件(deleting the profiles.ini file)轻松解决此问题。
4] 读取配置文件失败
当Firefox核心程序文件出现问题时，您会收到此错误。解决此问题的唯一方法是重新安装Firefox。确保(Make)删除默认位于以下位置之一的Firefox安装目录：
- C:程序文件Mozilla Firefox
- C:程序文件 (x86)Mozilla Firefox
5] XULRunner – 错误
“XULRunner – Error: Platform version <x.x.x.x> is not compatible with minVersion <x.x.x.x>””
这里 ””取决于版本号。
如果您在软件更新后看到此消息，请使用其他浏览器从Firefox下载页面下载Firefox安装程序 。删除Firefox 配置文件(Firefox Profile)，然后重新安装。
6]打开文件写入时出错...
如果您收到“错误打开文件以写入...”(Error opening file for writing…”)作为错误消息，您将需要管理员来修复它。您可以右键单击Firefox快捷方式并以管理员身份运行它，或者让您的管理员为您以管理员身份运行它。
7]禁用防病毒(Disable Antivirus)和互联网(Internet)安全解决方案。
很多时候，这些解决方案会阻止应用程序。Firefox可能已被您在计算机上使用的防病毒和Internet安全解决方案阻止。禁用，然后尝试启动Firefox。如果可行，您需要确保将Firefox列入白名单。
8] Firefox在启动时不断崩溃
除了重新安装Firefox之外，您在这里无能为力。您可以尝试从安全模式(Safe Mode)开始，但这对找出问题没有多大帮助。
您可以做的一件事是从其发行说明中检查与最新版本 Firefox 的任何软件兼容性问题( their release notes.)。(Firefox)
9]更新处理器微码
既然我们确实看到了，我们大多数人都忘记了即使是处理器也带有一套编程，而且它们也可能有错误。例如，现代x86处理器包含实现对x86指令集的支持的内部代码。这些代码称为微码，如果其中存在问题。
解决此问题的唯一方法是更新 BIOS 或 UEFI。 (updating BIOS or UEFI. )请务必与您的 OEM 确认硬件级别升级。
10]寻求帮助
最后，确保继续发送崩溃报告。每次Firefox崩溃时， Mozilla Crash Reporter对话框都会出现。它允许您发送崩溃报告。请(Make)务必这样做，因为这将有助于为您解决问题。
当您在社区寻求帮助时，您可以附上崩溃报告。
由于Firefox没有为您启动，您可以转到 %APPDATA%\Mozilla\Firefox\Crash Reports\submitted\并从那里上传文件。使用 查看(View) 菜单按日期排列文件并记下最新文件。
PS：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。如果Mozilla Firefox 在 Windows(Firefox Freezes on Windows)(Firefox Freezes on Windows) 计算机上冻结，这篇文章将对您有所帮助。
Firefox keeps crashing on Windows 11/10 PC
If your Mozilla Firefox browser is frequently crashing on Windows 11/10/8/7, maybe on ѕtartup, or if the tab crash a lot, then in this guide, we will help you resolve most of the Fіrefоx crash issues.
Firefox keeps crashing on Windows 11/10 PC
In this guide we are covering these scenarios:
- Firefox won’t start
- No Error messages
- With Error messages.
- Firefox keeps crashing at startup
Firefox won’t start
If the Firefox windows don’t open, or you get an error message when trying to start Firefox, here is how you can fix it.
No Error Message:
- Restart your computer once.
- If your internet security software includes a “Virtual Browsing” feature, make sure to disable that feature, and clear the virtual cache.
- If it stopped working after installing an add-on, then you need to use Safe Mode. Hold down Shift-key and then double click on Firefox shortcut.
- Lastly, try creating a new Firefox Profile and then launch it.
With Error Messages
1] Mozilla Crash Reporter
If you see this window after you Start Firefox, then check out our guide – Common solutions to diagnose and fix problems in Firefox.
2] Firefox is already running but is not responding
If Firefox is already running but is not responding, then the problem is that your profile in Firefox cannot let go of the Profile Lock. In simple words, If a process puts a lock on certain files so nobody else can use it. Whenever an application is closed, it quits access to files it uses. In our case, Firefox may have shut down abnormally, leaving the lock in place.
3] Your Firefox profile cannot be loaded. It may be missing or inaccessible
This happens when some files in Cache may get corrupted or damaged in your profile. You can easily fix this by deleting the profiles.ini file.
4] Failed to read the configuration file
When there is a problem with the Firefox core program files, you get this error. The only way to resolve this is by reinstalling Firefox. Make sure to delete the Firefox installation directory, found in one of these locations by default:
- C:\Program Files\Mozilla Firefox
- C:\Program Files (x86)\Mozilla Firefox
5] XULRunner – Error
“XULRunner – Error: Platform version <x.x.x.x> is not compatible with minVersion <x.x.x.x>””
Here “<x.x.x.x>” depends on version number.
If you see this message after a software update, use another browser to download the Firefox installer from the Firefox download page. Delete the Firefox Profile, and then reinstall it.
6] Error opening file for writing…
If you receive “Error opening file for writing…” as an error message, you will need an administrator to fix it. You can right-click on Firefox shortcut and run it as administrator or ask your admin to run this as Administrator for you.
7] Disable Antivirus & Internet security solutions.
Many a time these solutions block applications. It is possible that Firefox has been blocked by antivirus & Internet security solutions you are using on the computer. Disable, and try to start Firefox. If it works, you need to make sure to whitelist Firefox in their list.
8] Firefox keeps crashing at startup
Not much you can do here is except to reinstall Firefox. You can try starting in Safe Mode, but that doesn’t help much to figure out the issue.
One thing you can do is check any software compatibility issue with the latest version of Firefox from their release notes.
9] Update Processor Microcode
Since we do see it, most of us forget that even processor comes with a set of programming, and they can also have bugs. For example, modern x86 processors contain internal code that implements support for the x86 instruction set. These codes are called microcode, and if there is an issue in there.
The only to fix this is by updating BIOS or UEFI. Do make sure to check with your OEM about hardware level upgrade.
10] Ask for Help
Lastly, make sure to keep sending a crash report. Every time Firefox crashes, Mozilla Crash Reporter dialog box appears. It lets you send a crash report. Make sure to do as it will help to resolve the issue for you.
When you ask for help in the community, you can attach the crash report.
Since Firefox is not starting for you, you can go to %APPDATA%\Mozilla\Firefox\Crash Reports\submitted\ and upload files from there as well. Use the View menu to arrange the files by date and note the newest file.
PS: 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. This post will help you if Mozilla Firefox Freezes on Windows computer.
