隐私已成为几乎每个人的主要问题。很少有人愿意在登录互联网时泄露他们的个人信息。幸运的是，Firefox可以通过多种方式帮助您维护在线隐私。有很多Firefox 附加组件(Firefox Add-ons)可供选择，以保护您的在线隐私。
在本文中，我们将介绍一些可用于保护在线数据的最佳Firefox隐私插件。大多数这些选项现在都可以在Firefox for PC 和Android上使用。
注意：(Note: )此列表中的大多数附加组件也可用于Google Chrome和Opera（Firefox 特定(Firefox-specific)功能除外）。如果您是Safari用户（无论是Mac还是 iOS），请查看我们的Safari 隐私指南(Safari privacy guide)。
HTTPS 确保在您的浏览器和网站之间传输的数据是加密的( data transmitted between your browser and a website is encrypted)。这意味着浏览更加安全，因为传输的信息都不会被截获。HTTPS Only 确保您的浏览器将仅连接到启用HTTPS的站点。
以前，为此目的推荐使用HTTPS Everywhere扩展，但由于 Firefox 的内置HTTPS Only具有相同的功能，我们已在此列表中替换它（即使它在技术上不是附加组件）。
仅激活 HTTPS：
- 打开火狐浏览器。
- 单击(Click)窗口右上角的三个水平线，然后选择设置(Settings)。
- 选择隐私和安全(Privacy & Security)。
- 向下滚动(Scroll)到显示 HTTPS Only Mode 的位置，然后单击(HTTPS Only Mode)Enable HTTPS Only Mode in All Windows旁边的复选标记。
2.uBlock起源(uBlock Origin)
uBlock Origin的开发人员称其为“广谱内容拦截器”，而不仅仅是广告拦截器。uBlock 阻止跟踪器、广告、弹出窗口和硬币矿工。它还通过从工具栏中选择元素 zapper 模式来删除特定的页面元素。
除了这些功能之外，uBlock Origin还允许您在网站上本地和全局阻止JavaScript元素。(JavaScript)要启用此功能，您需要使用 uBlock 的高级模式。
以前，ClearURLs插件是推荐的隐私扩展，它从URL(URLs)中删除跟踪元素。但是，uBlock Origin现在包括AdGuard URL 跟踪保护(AdGuard URL Tracking Protection)，它可以完成相同的工作，这意味着您只需要一个扩展程序。
uBlock Origin具有所有广告拦截器的最佳性能。它也是开源的，Github上的各种开发人员都在为这个插件做出贡献。其他广告拦截器通常是封闭源代码并将用户数据出售给第三方公司（例如Ghostery）。
uBlock Origin可能是整体上最好的隐私插件。如果您使用 uBlock，则不需要类似的附加组件，如Privacy Badger、DuckDuckGo Privacy Essentials和NoScript Security Suite 。但是，如果 uBlock 不适合您，这些都是不错的选择。
3.多账户容器(Multi-Account Containers)
Multi-Account Containers是一个Mozilla Firefox 附加组件，(Mozilla Firefox Add-on)可将您的在线活动分成不同的“帐户”。这有助于防止网站能够在线跟踪您的浏览习惯。
使用Multi-Account Containers，您可以将您的浏览活动（以及 cookie）分离到单独的容器中。例如，您可能会使用Facebook容器、搜索引擎容器和Amazon容器。这样，一个网站将无法了解您在另一个网站上的活动，因此您的搜索结果不会影响您收到的广告。
Multi-Account Containers的另一个额外功能是您可以同时登录同一个站点的多个帐户，为您提供更好的浏览体验。
互联网上发生的大多数跟踪都是通过 cookie 进行(happens via cookies)的。它们在各种网站上都很有用（例如记住您的购物车）。尽管如此，它们仍允许网站跟踪您的活动并窃取您的个人数据。
多帐户容器(Multi-Account Containers)可以帮助管理这些并防止他们为您构建特定的角色，但这并不是故事的结局。为了增加您的隐私，您应该经常管理和删除不需要的 cookie。
Cookie AutoDelete是一个Firefox扩展程序，可在您每次关闭网站或标签时删除 cookie。但是，如果您想保留网站的 cookie，可以将网站添加到白名单中。这使您可以更严格地控制允许跟踪您的网站。
但是，从Firefox 89开始，Mozilla提供了全面 Cookie 保护(Total Cookie Protection)功能（通过增强跟踪保护(Enhanced Tracking Protection)的“严格”设置启用）。此隐私功能称为动态第一方隔离(First Party Isolation)(dFPI)，它为每个网站的 cookie 创建单独的位置，以防止跟踪器和指纹识别器跟踪您。
5.本地CDN(LocalCDN)
LocalCDN是推荐的浏览器扩展程序，可补充 uBlock（或其他广告拦截(another ad blocker)器）。许多网站利用Google(Google)和Cloudflare等公司的第三方内容交付网络 ( CDN(CDNs) )来加载资源。但是，这些公司可以通过此连接跟踪您的活动。
LocalCDN通过防止您的数据通过CDN请求泄露来改善您的隐私。作为奖励，它还可以提高您的带宽。但是，它的功能可以破坏特定的站点。
Decentraleyes是用于相同目的的替代插件。但是，LocalCDN的更新频率更高，并且拥有更广泛的数据库。
请记住，Firefox 的全面 Cookie 保护(Total Cookie Protection)已经在您的 Web 浏览器中隔离了站点数据，因此CDN(CDNs)只能访问您的 IP。甚至可以通过屏蔽您的 IP 来屏蔽这一点，这通常是隐私专家推荐的。
隐私至上
如今，在线隐私保护是您可以做的最重要的事情之一。无论您走到哪里，您的个人信息都会成为目标。虽然它通常仅用于向您投放相关广告，但这也意味着您的身份和个人信息存在风险。
借助高质量的 VPN(high-quality VPN)、正确的浏览器设置和一些出色的隐私插件，您可以确保您的数据安全。
5 Best Firefox Privacy Add-ons for Online Safety
Privacy has become a major issue for almost everуone. Few peoplе are happy to gіve their рersonal informаtion away whenever theу sign onto the internet. Luckily, Firefox helps you maintain yоur privacу online in several ways. There are plenty of Firefox Add-ons to choose from to protect your online privacy.
In this article, we’ll cover some of the best Firefox privacy add-ons you can use to protect your online data. Most of these options are now available on Firefox for PC and Android.
Note: Most add-ons in this list are also available for Google Chrome and Opera (except for the Firefox-specific features). If you’re a Safari user (whether Mac or iOS), check out our Safari privacy guide.
1. HTTPS Only (in-built version of HTTPS Everywhere)
HTTPS ensures that data transmitted between your browser and a website is encrypted. This means that browsing is more secure because none of the transmitted information can be intercepted. HTTPS Only ensures that your browser will only connect to sites with HTTPS enabled.
Previously, the HTTPS Everywhere extension was recommended for this purpose, but as Firefox’s in-built HTTPS Only has the same functionality, we’ve replaced it in this list (even though it isn’t technically an add-on).
To activate HTTPS Only:
- Open the Firefox browser.
- Click the three horizontal lines at the top-right of the window and select Settings.
- Select Privacy & Security.
- Scroll down to where it says HTTPS Only Mode and click the checkmark next to Enable HTTPS Only Mode in All Windows.
The developers of uBlock Origin call it a “wide-spectrum content blocker” rather than simply an ad blocker. uBlock blocks trackers, ads, pop-ups, and coin miners. It also removes specific page elements by selecting the element zapper mode from the toolbar.
Beyond these functions, uBlock Origin also allows you to block JavaScript elements both locally and globally on a website. To enable this, you need to use the advanced mode of uBlock.
Previously, the ClearURLs add-on was a recommended privacy extension that removed tracking elements from URLs. However, uBlock Origin now includes AdGuard URL Tracking Protection which does the same job, meaning you only need one extension.
uBlock Origin has the best performance of any adblocker. It’s also open-source, with various developers on Github contributing to the add-on. Other ad blockers are often closed-source and sell user data to third-party companies (e.g., Ghostery).
uBlock Origin is probably the overall best privacy add-on. Similar add-ons like Privacy Badger, DuckDuckGo Privacy Essentials, and NoScript Security Suite are unnecessary if you use uBlock. However, if uBlock doesn’t work for you, these are great alternatives.
Multi-Account Containers is a Mozilla Firefox Add-on that separates your online activity into different “accounts.” This helps to prevent websites from being able to track your browsing habits online.
With Multi-Account Containers, you can separate your browsing activity (and therefore the cookies) into separate containers. For instance, you might use a Facebook container, search engine container, and Amazon container. This way, one website won’t be able to know about your activity on another site, so your search results won’t influence the advertisements you receive.
Another bonus function of Multi-Account Containers is that you can simultaneously sign in to multiple accounts for the same site, giving you a better browsing experience.
Most of the tracking that occurs on the internet happens via cookies. They can be useful on various websites (such as remembering your shopping cart). Still, they allow websites to track your activity and siphon your personal data.
Multi-Account Containers can help manage these and prevent them from building a specific persona for you, but that isn’t the end of the story. To increase your privacy, you should constantly manage and delete unwanted cookies.
Cookie AutoDelete is a Firefox extension that deletes cookies every time you close a website or tab. However, you can add sites to a whitelist if you want to keep their cookies. This gives you tighter control over which websites you allow to track you.
However, as of Firefox 89, Mozilla offers the Total Cookie Protection feature (enabled via the “strict” setting for Enhanced Tracking Protection). This privacy feature is known as dynamic First Party Isolation (dFPI), and it creates a separate location for each website’s cookies to prevent trackers and fingerprinters so that they do not track you.
LocalCDN is a recommended browser extension that complements uBlock (or another ad blocker). Many websites utilize third-party content delivery networks (CDNs) from companies such as Google and Cloudflare to load resources. However, these companies can track your activity via this connection.
LocalCDN improves your privacy by preventing your data from being leaked through CDN requests. As a bonus, it also enhances your bandwidth. However, its function can break specific sites.
Decentraleyes is an alternative plug-in that serves the same purpose. However, LocalCDN is updated far more frequently and has a more extensive database.
Keep in mind that Firefox’s Total Cookie Protection already isolates site data in your web browser so that the CDNs can only access your IP. And even this can be shielded by masking your IP, which is generally recommended by privacy experts anyway.
Privacy is Paramount
These days, privacy protection online is one of the most important things you can do. Your personal information is targeted everywhere you go. While it’s usually used simply to target you with relevant ads, it also means that your identity and personal information are at risk.
With a high-quality VPN, the right browser settings, and some great privacy add-ons, you can ensure that your data is secure.
