Chrome is moving towards a new experience that lets people make an informed choice with respect to third-party cookies

谷歌正在转向一种新的用户体验，其核心目标是让用户对第三方Cookie有更清晰、知情的控制权。过去，浏览器默认允许网站设置Cookies，包括第三方Cookies，这些小数据文件通常用于跟踪用户的行为和提供个性化内容。然而，随着隐私意识的增强和技术的发展，谷歌采取了措施强化用户的隐私设置：

1. **Enhanced Privacy Controls**: Google推出了更严格的Cookie策略，例如在Chrome 84及更高版本中引入了“Cookieless Third Party Isolation”（无Cookie的第三方隔离）。这意味着即使网站设置了第三方Cookie，它们将无法直接关联到特定用户。

2. **Permission Requests**: 用户现在在首次访问网站时会被询问是否允许存储Cookies，尤其是对于那些对用户有潜在追踪影响的第三方Cookie。这样，用户可以自主决定哪些网站可以获取他们的信息。

3. **Privacy Badges**: Google还引入了“Privacy Badges”，这是一种可视化信号，表明网站如何处理Cookie以及其对用户隐私的影响，帮助用户做出更明智的选择。

这种新体验旨在平衡网站功能和个人隐私之间的需求，让互联网用户能更好地掌控自己的数据安全。用户可以根据这些改变调整浏览器设置，并了解他们的Cookie选择如何影响浏览体验。

Chrome is moving towards a new experience that allows users to choose to browse without third-party cookies.

### Chrome 浏览户新体验：不使用第三方 Cookie

为了增强隐私保护并响应用户需求，Chrome 推出了新的浏览体验，允许用户选择不依赖于第三方 Cookie 进行浏览。这一功能旨在减少跨站跟踪行为的同时保持网页的功能性和用户体验。

#### 用户控制权提升

新版Chrome让用户能够更精细地管理Cookie设置。具体来说，在浏览器的隐私设置中新增了一个选项，使用户可以轻松关闭或限制第三方Cookie的使用[^1]。这意味着当访问网站时，默认情况下不会加载来自其他域名的Cookie数据，从而减少了潜在的数据收集风险。

#### 插件支持加强

除了内置的选择机制外，还有多种扩展程序可帮助进一步管理和屏蔽不必要的第三方Cookie。例如AdBlock Plus能有效防止广告及其关联的追踪技术；而Privacy Badger则会依据个人上网习惯智能判断哪些请求应该被阻断[^2]。这些工具配合官方提供的偏好设定一起工作，共同构建起一道坚固的安全屏障。

#### 特定场景下的调整建议

对于某些特定应用环境如企业内部部署的应用程序接口调用等场合，可能遇到因禁用了第三方Cookies而导致的功能障碍问题。针对这种情况，Google也给出了相应的解决方案——即在隐身模式下更改默认策略为接受全部类型的Cookies（原本是拒绝），以此确保必要的交互操作得以正常执行[^3]。

import browser_cookie3 as bc

def check_third_party_cookies():
    try:
        cookies = list(bc.chrome(domain_name='example.com'))
        third_party_present = any('.com' not in c.domain and '.org' not in c.domain for c in cookies)
        return "Third party cookies are enabled." if third_party_present else "Only first-party cookies present."
    except Exception as e:
        return str(e)

print(check_third_party_cookies())

Third-party cookie will be blocked

Third-party cookies are small pieces of data that are stored on a user's browser by websites other than the one they are currently visiting. These cookies are commonly used for tracking and advertising purposes. However, due to privacy concerns, many web browsers are moving towards blocking third-party cookies by default.

Blocking third-party cookies means that websites will no longer be able to access or store cookies from domains other than their own. This can have several implications:

1. Enhanced privacy: Blocking third-party cookies helps protect user privacy by preventing websites from tracking their online activities across different sites.

2. Impact on advertising: As third-party cookies are commonly used for targeted advertising, blocking them can affect the ability of advertisers to deliver personalized ads based on user behavior.

3. Changes in website functionality: Some websites rely on third-party cookies for various functionalities such as social media integration, analytics, or personalized content. Blocking these cookies may impact the functionality of such websites.

4. Shift towards alternative tracking methods: With the decline of third-party cookies, alternative methods for tracking and targeting users are being explored, such as first-party cookies, contextual advertising, and consent-based tracking.
