如果您发现Windows PC 上的Mozilla Firefox网络浏览器运行不流畅，您可以使用刷新 Firefox^{(Refresh Firefox)}功能将您的浏览器设置重置并恢复为Windows 11/10中的默认值。较早的版本具有基本相同的“重置 Firefox^{(Reset Firefox)} ”按钮，但在最近的版本中，您具有“刷新 Firefox^{(Refresh Firefox)} ”功能。

我最近在我的Windows x64 PC上安装了^{(Windows x64 PC)}Firefox x64 t ，然后卸载了我的旧Firefox x86。当我启动新的Firefox x64时，我在浏览器底部看到了以下通知——看起来你已经重新安装了 Firefox。^{(Looks like you’ve reinstalled Firefox. Want us to clean it up for a fresh like-new experience)}希望我们清理它以获得全新的体验-在另一端使用刷新 Firefox按钮。^{(Refresh Firefox)}

将 Firefox 重置或刷新为默认值

我决定让我的Firefox重新开始，并在通知栏上单击此处的刷新 Firefox按钮，但要手动^{(Refresh Firefox)}刷新 Firefox^{(Refresh Firefox)}，您还可以执行以下操作：

1. 打开火狐
2. 单击 3 行设置菜单
3. 点击帮助
4. 选择故障排除信息
5. 最后，单击刷新 Firefox^{(Refresh Firefox)}按钮。

此图片说明了点击的位置：

您将看到故障排除^{(Troubleshooting)}信息页面右侧的按钮：

接下来将打开以下窗口。

当您执行此过程时，Firefox将：

1. 创建一个新的配置文件文件夹
2. 浏览器^(Browser)设置将恢复为默认值
3. Firefox设置和个人数据将存储在新的配置文件文件夹中。

以下内容将被删除^(removed)：

• 扩展程序和主题将与扩展程序数据一起被删除
• 插件，不会被删除，但会被重置
• 自定义将被删除
• 网站权限
• 修改^(Modified)的首选项、添加的搜索引擎、DOM存储、安全证书和设备设置、下载操作、插件设置、工具栏自定义、用户样式和社交功能也将被删除。

以下内容不会被删除^{(not be removed)}。它们将被保存和备份：

1. 饼干
2. 浏览记录
3. 下载历史
4. 书签
5. 保存的表单历史
6. 保存的密码
7. 个人词典
8. 打开窗口和选项卡。

所有其他选项和设置将重置为默认值，您将看到导入完成^{(Import Complete)}窗口。

导入并保存这些设置后，该过程将运行至完成。

Once the refresh is completed, restart your Firefox and check how it performs. I did see a material difference! Do let us know if you noticed a difference.

Firefox用户意识到他们最喜欢的浏览器（与大多数其他浏览器一样）在一段时间内会变得缓慢、死机或崩溃。虽然人们总是可以尝试解决此类Firefox 冻结或崩溃^{(Firefox Freezing or Crashing)}或Firefox 减慢^{(Firefox slowing down)}问题，但如果它对您不起作用，那么在考虑重新安装之前，刷新Firefox是您应该考虑的最后也是最好的选择。

如果您愿意，您还可以在线调整您的 Firefox 浏览器。

Reset or Refresh Firefox browser settings to default in Windows 11/10

If you find that your Mozilla Firefox web browser on your Windows PC is not running smoothly, you can use the Refresh Firefox feature to reset and restore your browser settings to the default value in Windows 11/10. Earlier one had the Reset Firefox button which essentially did the same, but in the recent versions, you have the Refresh Firefox feature.

I recently installed Firefox x64t on my Windows x64 PC, and then uninstalled my old Firefox x86. When I launched the new Firefox x64, I saw the following notification at the bottom of the browser – Looks like you’ve reinstalled Firefox. Want us to clean it up for a fresh like-new experience – with a Refresh Firefox button at the other end.

Reset or Refresh Firefox to default

I decided to give my Firefox a new start and clicked on the Refresh Firefox button here on the notification bar, but to Refresh Firefox manually, you can also do the following:

1. Open Firefox
2. Click on 3-lined Settings Menu
3. Click on Help
4. Select Troubleshooting information
5. And finally, click on the Refresh Firefox button.

This image explains the locations for the clicks:

You will see the button on the right side of the Troubleshooting information page:

The following window will open next.

When you carry out this process, Firefox will:

1. Create a new profile folder
2. Browser settings will be restored to their defaults
3. Firefox settings and personal data will be stored in the new profile folder.

The following will be removed:

• Extensions and themes will be removed along with extension data
• Plugins, will not be removed but will be reset
• Customizations will be removed
• Website permissions
• Modified preferences, added search engines, DOM storage, security certificate and device settings, download actions, plugin settings, toolbar customizations, user styles and social features will also be removed.

The following will not be removed. They will be saved and backed up:

1. Cookies
2. Browsing History
3. Download History
4. Bookmarks
5. Saved Form History
6. Saved passwords
7. Personal dictionary
8. Open windows and tabs.

All other options and settings will be reset to the default and you will see a Import Complete window.

Once these settings are imported and saved, the process will run to its completion.

Once the refresh is completed, restart your Firefox and check how it performs. I did see a material difference! Do let us know if you noticed a difference.

Firefox users are aware of how their favorite browser – like most others – tends to go slow, freeze or crash over a period of time. While one can always try and troubleshoot such Firefox Freezing or Crashing or Firefox slowing down issues, if it does not work for you, refreshing Firefox is the last and best option you should consider, before thinking of a reinstall.

If you wish, you can also tune up your Firefox browser online.
