"Clear your browsing history" is the most commonly repeated browser privacy advice, and also the least complete — a browser's privacy footprint is shaped by several other settings most people never touch.
The pieces beyond history
- Storage. Cookies, local storage, and IndexedDB data can persist identifying information well beyond what clearing "history" alone removes.
- Permissions. Location, camera, microphone, and notification permissions granted to specific sites remain active until explicitly revoked — worth periodically reviewing.
- Fingerprinting exposure. Your browser's configuration — fonts, screen size, installed plugins, timezone — contributes to a fingerprint that clearing history does nothing to change. See Browser Fingerprinting.
- Network data. DNS and WebRTC behavior can reveal information independent of anything stored locally in the browser — see the dedicated leak-test guides for these.
- Synchronization. If you're signed into browser sync, your browsing data may be linked across devices and stored by the browser vendor, regardless of local clearing.
- Extensions. Installed extensions can have broad access to page content and browsing activity — worth periodically auditing what's installed and why.
- Updates. An outdated browser can carry known vulnerabilities that undermine privacy and security measures otherwise in place.
A more complete approach
Rather than relying on history-clearing alone, periodically reviewing permissions, auditing extensions, keeping the browser updated, and understanding what fingerprinting and network-level exposure look like (see the related guides linked above) gives a much more complete picture of your actual browser privacy posture.
FAQ
Does private/incognito browsing address all of this?
No — see Does Incognito Mode Hide Your IP Address? and Private Browsing Limitations for what it actually covers and what it doesn't.
