You don't need to switch to an obscure browser or memorize a dozen new tools to meaningfully reduce how much of your browsing gets tracked. These seven changes take a few minutes total and won't break the sites you use every day — a fair trade for a real reduction in cross-site tracking.
1. Block third-party cookies
Third-party cookies — set by a domain other than the one you're visiting — are the backbone of cross-site ad tracking; they're how an ad network can tell that the same person who looked at hiking boots on one site is now reading a news article on another. Every major browser lets you block them while still allowing first-party cookies (the ones that keep you logged into a site), so this rarely breaks normal browsing. Look for it under Privacy and Security settings.
2. Turn on "Do Not Track" or its modern equivalent
The original Do Not Track header was largely ignored by advertisers, so most browsers have replaced or supplemented it with stronger built-in tracking protection — Firefox's Enhanced Tracking Protection and Safari's Intelligent Tracking Prevention actively block known trackers rather than just requesting they not track you. Make sure this is set to at least "Standard" or "Balanced," not disabled.
3. Use a search engine that doesn't build a profile on you
Your search history is one of the most revealing data sets you generate. Switching your default search engine to one that doesn't log searches tied to your identity (several privacy-focused options exist) removes a significant source of profiling without requiring you to change how you browse at all.
4. Review site permissions periodically
Over months and years, you accumulate permissions granted to sites for location, camera, microphone, and notifications — many of which you approved once and forgot about. Your browser's site settings page lets you review and revoke these in bulk. It's worth doing every few months, especially for location access, which is one of the more sensitive permissions to leave granted indefinitely.
5. Clear cookies and site data on a schedule, not never
You don't need to clear cookies after every session — that breaks logins and preferences constantly. But letting them accumulate indefinitely means you're carrying years of tracking identifiers. A reasonable middle ground is clearing site data every few months, or configuring your browser to automatically clear cookies from sites you haven't visited in a while.
6. Disable browser sync for sensitive profiles, or use a separate profile
If you share a computer, or you use the same browser profile for both personal and work browsing, consider creating a separate browser profile for the two. Most browsers support multiple profiles natively now, each with its own cookies, history, and extensions — a clean way to keep, for example, work-related tracking separate from personal browsing.
7. Check what your extensions can actually see
Browser extensions are one of the most overlooked privacy risks, because a poorly vetted extension can technically read and modify every page you visit — often broader access than the extension actually needs for its stated function. Periodically review your installed extensions' permissions, and remove anything you don't remember installing or actively using.
What these settings won't do
It's worth being honest about the limits here: these changes reduce common tracking methods, but they don't make you anonymous, and they won't stop a site you're logged into from knowing what you do on that specific site. If you need stronger anonymity — for a specific, sensitive reason — that's a different (and more disruptive) set of tools entirely, like a dedicated privacy-focused browser combined with a trustworthy VPN.
