您的Mozilla Firefox浏览器在(Mozilla Firefox)Windows 10/8/7 PC上是否有问题？在这篇文章中，我们将分享一些常见的解决方案来诊断和修复Firefox中的问题。应用这些建议，您可以自己解决大部分问题。
修复 Firefox 问题和问题
自己了解一些故障排除总是一个好主意。由于我们只是在浏览器中解决问题，因此并不难。
1]以安全模式启动Firefox
Firefox 安全模式(Firefox Safe Mode)会暂时关闭硬件加速、重置一些设置并禁用附加组件。这使您可以评估是否有任何主题、附加组件或硬件加速是问题的原因。进入安全模式：
- 单击菜单按钮 > 帮助
- 选择 禁用加载项(Add-ons Disabled)重新启动(Restart)
- Firefox将启动Firefox 安全模式(Firefox Safe Mode)对话框
- 单击以安全模式开始
现在尝试重新创建问题并查看它是否仍然存在。如果是，那么这些设置不是原因，如果是，您将不得不禁用个别设置并检查导致问题的原因。
2]运行恶意软件扫描
如果您收到很多烦人的弹出窗口、搜索被重定向到另一个站点、 网页(Web)没有完全加载等等，这可能是一个恶意软件问题。确保(Make)您的 PC 上有最好的恶意软件扫描程序(best malware scanners)之一来删除它。
您可能必须将Windows 10 启动到安全模式，然后使用Windows Defender扫描恶意软件。
3]重置/刷新Firefox
Firefox中多次更改设置会导致问题。如果您无法确定是哪个问题导致您出现问题，最好重置 Firefox。它也被称为Refresh Firefox。如果这没有帮助，您还可以选择 删除 Firefox 首选项文件。(delete the Firefox preference files.)
当您刷新时，它将删除扩展和主题、网站权限、修改的首选项、添加的搜索引擎、DOM存储、安全(Security)证书、设备设置以及任何工具栏自定义。
您需要找到并删除文件 prefs.js 或将其重命名为 prefs.js.old 之类的名称。如果您看到任何其他“JS”文件，也请重命名它们。重新启动火狐(Firefox)。
4]对扩展、主题和硬件加速进行故障排除(Troubleshoot)
这部分通常需要很多时间，因为您需要检查三个单独的事情。假设您已经尝试过安全模式(Safe Mode)和刷新(Refresh)，让我们找出其余的。
- 单击(Click)菜单按钮并选择加载项以启动加载项管理器(Add-ons Manager)选项卡。
- 禁用所有扩展。
- 现在一一开启，看看有没有问题。
如果在启用一个特定扩展后出现问题，那么您有来源。您可以尝试更新插件或完全卸载它。
您还可以选择重置(Reset)和更新(Update)所有附加组件选项只是为了抓住机会。
接下来，切换到默认主题，并检查问题是否仍然存在。
- 单击(Click)菜单按钮并选择加载项 >Add-ons Manager > Themes Panel
- 选择默认主题，然后单击启用按钮。
- 如有必要，重新启动 Firefox。
检查问题是否仍然存在。如果没有，那主题就是你的问题。
接下来，关闭硬件加速(turn off Hardware Acceleration)。如果问题不再出现，则需要更新显卡驱动程序(update the Graphics Driver)。看看是否可以解决，否则您可以始终保持硬件加速关闭。
5]解决安全错误
如果您收到以下任何错误代码：
在HTTPS网站上，那么它的证书有问题。您 PC 上的某些程序正在替换网站的证书，因此Firefox无法信任。
提示(TIP)：如果您在 Firefox 中打开about : (Firefox)support(about:support)，您会看到很多信息，这些信息可以帮助您解决Firefox问题。
除此之外，还有一些一般的故障排除技巧。它包括清除缓存、cookies、重新安装Firefox，甚至创建新的 Firefox 配置文件(creating a new Firefox Profile)。如果您在使用媒体播放器时遇到问题，您也可以尝试修复Adobe Flash 问题(Adobe Flash issues)。

Fix Firefox problems & issues on Windows PC
Is yoυr Mozilla Firefox browser having problems on Windows 10/8/7 PC? In this post, we will share some common solutions to diagnose and fix problems in Firefox. Applying these suggestions, you can resolve most of the problems on your own.
Fix Firefox problems and issues
It’s always a good idea to know a bit of troubleshooting on your own. Since we are just troubleshooting the issue in the browser, it’s not tough.
1] Start Firefox in Safe Mode
Firefox Safe Mode temporarily turns off hardware acceleration, resets few settings, and disables add-ons. This allows you to assess if any of the themes, add-ons, or the hardware acceleration are the cause of the problem. To get into safe mode:
- Click the menu button > Help
- Select Restart with Add-ons Disabled
- Firefox will start up with the Firefox Safe Mode dialog
- Click the Start in Safe Mode
Now try to recreate the issue and see if it still exists. If yes, then those settings are not the cause, if yes, you will have to disable individual settings and check what was causing the issue.
2] Run Malware Scan
If you are receiving a lot of annoying pop-ups, searches are redirected to another site, Web pages not loading completely, and so on, it could be a malware issue. Make sure you have one of the best malware scanners on your PC to remove it.
You may have to boot Windows 10 into Safe Mode and then use Windows Defender to scan for the malware.
3] Reset/Refresh Firefox
Many a time changed settings in Firefox cause problems. If you cannot figure out which is causing you a problem, its best to Reset Firefox. Its also called as Refresh Firefox. If this doesn’t help, you can also choose to delete the Firefox preference files.
When you Refresh, it will delete extensions and themes, website permissions, modified preferences, added search engines, DOM storage, Security certificate, device settings, and any toolbar customization.
You need to locate and delete the file prefs.js or rename it to something like prefs.js.old. If you see any other “JS” file, rename them as well. Relaunch Firefox.
4] Troubleshoot extensions, themes, and hardware acceleration
This part usually takes a lot of time as you need to check on three individual things. Assuming you have already tried Safe Mode and Refresh let’s figure out the rest.
- Click the menu button and choose Add-ons to launch the Add-ons Manager tab.
- Disable all the extensions.
- Now enable it one by one, and see if the problem exists.
If the problem occurs after enabling one particular extension, then you have the source. You can either try updating the add-on or uninstall it completely.
You can also choose to Reset & Update all the add-ons option just to take a chance.
Next, switch to the default theme, and check if the problem still exists.
- Click the menu button and choose Add-ons > Add-ons Manager > Themes Panel
- Select the default theme, then click the Enable button.
- Restart Firefox if necessary.
Check if the problem persists. If not, that theme is your problem.
Next, turn off Hardware Acceleration. If the problem doesn’t occur again, then you need to update the Graphics Driver. See if that fixes, else you can always keep the hardware acceleration turned off for good.
5] Troubleshoot Security Errors
If you receive any of these error codes:
on HTTPS websites, then its a problem with the certificates. Some program on your PC is replacing certificates of the websites, and hence Firefox is not able to trust.
TIP: If you open about:support in your Firefox, you will see a lot of information that may help you troubleshoot your Firefox problems.
