Start with separate browser profiles
The simplest privacy improvement is not a hidden setting. It is separation. Use one browser profile for personal accounts, one for work or school, and one for testing unfamiliar sites. Profiles separate cookies, history, extensions, and saved sessions, which makes cross-site tracking less convenient and reduces the chance that a risky extension sees everything you do.
This does not make you anonymous. Your internet provider, workplace network, or the websites you sign in to may still identify you. But profile separation is easy to maintain and does not usually break websites.
Review cookie settings carefully
Blocking every cookie sounds attractive, but it can break logins, shopping carts, bank sessions, and language settings. A practical approach is to block or limit third-party cookies, clear cookies for sites you no longer use, and keep first-party cookies for services you intentionally sign in to.
If your browser offers site-specific exceptions, use them sparingly. A site that stops working after third-party cookies are blocked may be depending on an embedded login, payment, or support provider. Decide whether the convenience is worth the added tracking surface.
Limit permissions by default
Camera, microphone, location, notifications, clipboard, and file-system permissions should be denied by default unless you need them. If you use video calls, grant camera and microphone access only to the meeting sites you trust. If a weather, map, or delivery site asks for location, consider typing a city or postal code instead.
Notifications deserve special attention. Many low-quality sites request notification permission so they can push ads or misleading alerts. Keep browser notifications off globally unless you have a clear reason to enable them.
Use fewer extensions
Extensions can improve privacy, but they can also read pages, change content, and create new risks. Keep only the extensions you understand and use. Remove coupon finders, unknown download tools, search helpers, and old extensions that have not been updated.
A good baseline is one reputable content blocker, a password manager extension from the password manager you use, and maybe a trusted note or reading tool. More extensions are not automatically more protection.
Choose search and sync settings intentionally
Search engines, browser sync, and account services can connect browsing activity across devices. Decide what you actually need to sync. Bookmarks and passwords may be useful; open tabs, history, addresses, and payment data may be unnecessary. If you share a family computer, avoid syncing a personal browser profile to the shared account.
For search, a privacy-focused search engine may reduce profiling, but it will not hide your activity from every party. Signed-in accounts, browser fingerprints, IP address, and device patterns can still matter.
Keep one clean fallback browser
Privacy settings sometimes break poorly built sites. Keep a second browser with minimal extensions for tasks that fail in your main browser, such as a government form, bank upload, or ticket purchase. Do not use the fallback browser for casual browsing. Its job is reliability, not daily exploration.
Monthly maintenance checklist
- Remove extensions you have not used recently.
- Clear cookies and permissions for sites you no longer trust.
- Check whether your browser is up to date.
- Review saved passwords and replace reused passwords.
- Delete old profiles that contain accounts you no longer use.
