如果您的网络浏览器遇到无法解决的严重问题，您可以将其重置为出厂默认设置。值得庆幸的是，大多数主流浏览器都有一个专用的重置按钮，可以让这个过程快速而直接。
继续阅读以了解如何将流行的桌面浏览器（如Google Chrome、Mozilla Firefox和Apple Safari ）重置为默认设置。
将谷歌浏览器重置(Reset Google Chrome)为出厂默认设置(Factory Defaults)
如果Google Chrome 崩溃、死机或无响应(Google Chrome crashes, freezes, or won’t respond)，或者您怀疑浏览器劫持者在起作用（例如，搜索引擎自动更改(the search engine automatically changes)或您看到不断的弹出警报），请考虑将浏览器重置为出厂默认设置。Chrome 重置：
- 恢复对启动页、主页、新标签页和搜索引擎的更改。
- 删除所有固定的选项卡。
- 禁用(Disables)所有活动的扩展和附加组件。
- 删除临时站点数据（cookie 和缓存）。
- 还原所有站点设置和权限。
重置Google Chrome浏览器不会删除您的书签、浏览历史记录和保存的密码。不过，我们建议您将任何个人数据上传到 Google 帐户(upload any personal data to a Google Account)，因此如果该过程未按计划进行，请进行备份。
1. 打开Chrome 菜单(menu)（选择浏览器窗口右上角的三个点）并选择Settings。
2.在 Chrome设置(Settings)页面的侧边栏上选择高级(Advanced)>重置和清理(Reset and cleanup)(PC) 或重置设置(Reset settings)( Mac )。

将Mozilla Firefox 重置(Reset Mozilla Firefox)为出厂默认设置(Factory Defaults)
与Chrome一样，Mozilla Firefox重置将删除所有自定义设置和浏览器缓存，同时保持密码和书签等个人数据完好无损。同样(Again)，最好将个人数据同步到您的 Firefox 帐户(sync personal data to your Firefox Account)，这样您就不会留下任何机会。
1. 打开Firefox 菜单(menu)（选择地址栏右上角的三个叠行）并选择帮助(Help)。
2. 选择更多故障排除信息(More troubleshooting information)。
3. 选择刷新 Firefox(Refresh Firefox)。
将Microsoft Edge 重置(Reset Microsoft Edge)为出厂默认设置(Factory Defaults)
Microsoft Edge是(Microsoft Edge)Windows 10和 11的默认基于 Chromium 的浏览器，只需简单地进入其设置(Settings)页面即可将其重置为出厂默认设置。您可以保留书签和密码，但最好将数据同步到Microsoft 帐户(Microsoft Account)，以防出现问题。这同样适用于macOS 的 Microsoft Edge 的可下载版本(downloadable version of Microsoft Edge for macOS)。

将Apple Safari 重置(Reset Apple Safari)为出厂默认设置(Factory Defaults)

清除缓存和 Cookie(Clear Cache and Cookies)
1.在菜单栏上选择Safari >清除历史记录。(Clear History)
2. 打开Clear(Clear )旁边的下拉菜单并选择All History。然后，选择清除历史记录(Clear History)。
禁用所有扩展(Disable All Extensions)

将Tor 浏览器重置(Reset Tor Browser)为出厂默认设置(Factory Defaults)
将极其注重隐私的Tor 浏览器(Tor Browser)恢复为出厂默认设置需要执行类似于Firefox的步骤（如上所示）。那是因为两个浏览器都运行在同一个代码库上。
1. 选择Tor 菜单(menu)按钮并选择标有帮助(Help)的选项。
2. 选择更多故障排除信息(More troubleshooting information)。
3. 选择刷新 Tor 浏览器(Refresh Tor Browser)。
将Opera 浏览器重置(Reset Opera Browser)为出厂默认设置(Factory Defaults)
如果您使用 Opera，您可以像其他 PC 或Mac上基于 Chromium 的浏览器一样重置它。
1. 打开Opera 菜单(menu)并选择设置(Settings)(PC) 或首选项(Preferences)(Mac)。

1. 打开勇敢(Brave) 菜单(menu)（选择窗口右上角的三个堆叠线）并选择设置(Settings)。
2. 选择侧栏上的其他设置(Additional settings)>重置设置。(Reset settings)
3. 选择将设置重置为其原始默认值(Reset settings to their original defaults)。
一个新的开始
将浏览器恢复为出厂默认设置后，您将不得不通过登录网站、重新激活扩展程序以及重新配置站点首选项和其他设置来重新开始。这应该提供有关先前问题背后的任何根本原因的线索。
例如，恶意扩展程序可能会导致您的默认搜索引擎页面发生更改。如果再次启用它会导致同样的问题，则必须从 Web 浏览器中卸载它。或使用反恶意软件实用程序(use an anti-malware utility)强行删除它。

Read on to learn what you must do to reset popular desktop browsers such as Google Chrome, Mozilla Firefox, and Apple Safari to default settings.
Reset Google Chrome to Factory Defaults
If Google Chrome crashes, freezes, or won’t respond, or if you suspect a browser hijacker is at play (e.g., the search engine automatically changes or you see constant pop-up alerts), consider resetting the browser to factory defaults. A Chrome reset:
- Reverts changes to the startup page, home page, new tab page, and search engine.
- Deletes all pinned tabs.
- Disables all active extensions and add-ons.
- Removes temporary site data (cookies and caches).
- Reverts all site settings and permissions.
Resetting the Google Chrome browser will not remove your bookmarks, browsing history, and saved passwords. Nevertheless, we recommend you upload any personal data to a Google Account, so have a backup if the procedure doesn’t go according to plan.
1. Open the Chrome menu (select three dots on the top-right of the browser window) and choose Settings.
2. Select Advanced > Reset and cleanup (PC) or Reset settings (Mac) on the sidebar of Chrome’s Settings page.
3. Select Restore settings to their original defaults > Reset settings to reset Chrome settings to factory defaults.
Reset Mozilla Firefox to Factory Defaults
Like with Chrome, a Mozilla Firefox reset will remove all customizations and the browser cache while keeping personal data such as passwords and bookmarks intact. Again, it’s best to sync personal data to your Firefox Account so that you don’t leave anything to chance.
1. Open the Firefox menu (select three stacked lines at the right corner of the address bar) and select Help.
2. Select More troubleshooting information.
3. Select Refresh Firefox.
Reset Microsoft Edge to Factory Defaults
Microsoft Edge, the default Chromium-based browser for Windows 10 and 11, can be reset to factory defaults with a brief dive into its Settings page. You get to keep your bookmarks and passwords, but it’s always a good idea to sync the data to a Microsoft Account in case something goes wrong. The same applies to the downloadable version of Microsoft Edge for macOS.
1. Open the Edge menu (select the three dots at the window’s top-right) and select Settings.
2. Select Reset Settings on the sidebar of Edge’s Settings menu.
3. Select Reset settings to their default values.
Reset Apple Safari to Factory Defaults
Safari, the default web browser for the Mac, does not come with a built-in option that you can use to reset the browser to factory defaults. Instead, you must clear your Safari browsing data, disable active extensions, and revert any customizations all by yourself.
Clear Cache and Cookies
1. Select Safari > Clear History on the menu bar.
2. Open the drop-down menu next to Clear and pick All History. Then, select Clear History.
Disable All Extensions
1. Select Safari > Preferences on the menu bar.
2. Switch to the Extensions tab and clear the boxes next to all active extensions.
Revert All Preferences to Defaults
1. Quit the Safari app.
2. Open Finder and select Go > Go to Folder on the menu bar.

4. Drag the following file into the Trash:
5. Next, visit the following folders and drag all files and subfolders inside to the Trash:

Reset Tor Browser to Factory Defaults
Restoring the extremely privacy-oriented Tor Browser to factory defaults involves running through steps similar to Firefox (as shown above). That’s because both browsers run on the same codebase.
1. Select the Tor menu button and choose the option labeled Help.
2. Select More troubleshooting information.
3. Select Refresh Tor Browser.
Reset Opera Browser to Factory Defaults
If you use Opera, you can reset it just like any other Chromium-based browser for the PC or Mac.
1. Open the Opera menu and select Settings (PC) or Preferences (Mac).
2. Select Advanced on the sidebar.
3. Scroll down to the bottom of the page. Then, select Reset settings to their original defaults.
Reset Browser Settings in Brave to Factory Defaults
Brave Browser is a lightweight Chromium alternative that you can quickly reset to factory defaults using the following steps.
1. Open the Brave menu (select three stacked lines on the top right of the window) and choose Settings.
2. Select Additional settings > Reset settings on the sidebar.
3. Select Reset settings to their original defaults.
A Fresh Start
After restoring your browser to factory defaults, you will have to start all over again by signing into websites, reactivating extensions, and re-configuring site preferences and other settings. That should provide clues about any underlying reasons behind previous issues.
For example, a rogue extension might be what’s causing your default search engine page to change. If enabling it again results in the same problem, you must uninstall it from your web browser. Or use an anti-malware utility to get rid of it forcibly.
