Before learning how to browse anonymously, understand what you're currently exposing:
- IP 位址: Every website sees your IP 位址, which reveals your approximate location (city-level), ISP, and can be linked to your real identity through your ISP's records.
- Browser fingerprint: Your screen resolution, installed fonts, browser version, operating system, timezone, language, and hardware configuration create a unique fingerprint. Over 90% of browsers have a unique fingerprint.
- Cookies and trackers: Third-party cookies follow you across websites. Google Analytics is on 85%+ of websites. Facebook's pixel tracks you even without a Facebook account.
- DNS queries: Your DNS requests (converting domain names to IP 位址) are typically sent to your ISP in plaintext, revealing every site you visit.
- 搜尋 history: Google stores every 搜尋 you make, linked to your account and IP 位址. This data is used for advertising and can be subpoenaed.
匿名 browsing addresses all of these leak points simultaneously.
