Browser Privacy Settings: Cookies and Trackers Explained Simply
Every website seems to show a cookie banner now, and many people click "Accept all" just to make it go away. Meanwhile, ads for something you searched yesterday follow you across different websites. Behind both of these are cookies and trackers.
Understanding the basics helps you make better choices about your privacy without breaking the websites you use. This guide explains what is going on and which settings are worth changing.
What Cookies Actually Are
A cookie is a small piece of data a website stores in your browser. Many cookies are useful: they keep you logged in, remember your language and keep items in your shopping cart. These are often called first-party cookies because they come from the site you are visiting.
Third-party cookies come from other companies embedded in the page, such as advertising and analytics networks. They can recognise you across many different websites, building a profile of your interests for targeted ads. This is the main privacy concern.
Browsers have been changing how they handle third-party cookies, and some block them by default. Websites also use other tracking techniques, so cookies are only part of the picture.
Other common tracking methods include tracking pixels in emails and pages, and fingerprinting, which identifies a browser from its settings and hardware details. Browser privacy protections increasingly try to limit these as well.
Understanding Cookie Banners
Cookie banners appear because privacy rules in many regions require websites to ask permission for non-essential tracking. When you see one, you usually have choices beyond "Accept all":
- Reject all or Necessary only, which allows only cookies required for the site to work
- Manage preferences, which lets you choose categories such as analytics or advertising
Choosing necessary-only cookies rarely breaks a website and limits tracking. It takes one extra click and becomes a quick habit.
If a website makes rejecting cookies very difficult, with hidden buttons or many steps, that tells you something about how it treats your data.
Settings Worth Changing in Your Browser
- Block third-party cookies in your browser's privacy settings, if not already blocked by default.
- Use tracking protection features, such as Firefox Enhanced Tracking Protection, Safari's Intelligent Tracking Prevention or Edge's tracking prevention levels.
- Review site permissions for location, camera, microphone and notifications, and remove ones you do not need.
- Clear browsing data occasionally, or set it to clear when you close the browser.
- Check extensions and remove any you do not recognise or no longer use.
Tip: website notification requests are a common source of spam and fake alerts. Block notification permissions unless you truly want them.
Private Browsing: What It Does and Does Not Do
Private or incognito mode does not save your browsing history, cookies or form data after you close the window. It is useful on shared computers or when you do not want searches saved on your device.
It does not make you invisible. Websites, your employer's network and your internet provider can still see activity. It does not protect you from malware or phishing. For extra privacy on public networks, see our guide to when you actually need a VPN.
Private mode is also useful for checking how a website looks to a new visitor, or for logging in to a second account temporarily without logging out of your main one.
Balance Privacy and Convenience
Very strict settings can break some websites, especially banking or payment pages that rely on cookies to keep you logged in. If a trusted site stops working, allow cookies for that specific site rather than turning protections off everywhere.
Remember that being logged in to big platforms in your browser lets them connect your activity across their services. Review the ad and activity settings in your Google, Microsoft, Apple or Meta accounts too, where you can limit personalised ads and delete activity history.
Privacy is a set of small habits rather than one big switch. Pair these settings with strong account security from our password manager guide.
Review these settings every few months, since browser updates sometimes add new options or change defaults, and a quick look keeps your choices in place.
FAQ
Should I delete all cookies regularly?
Clearing all cookies logs you out of sites. Many people prefer blocking third-party cookies and clearing data occasionally.
Is one browser more private than others?
Browsers differ in default protections. All major browsers offer privacy settings worth reviewing.
Do cookie banners mean the site is unsafe?
No. They are a legal and transparency requirement in many regions, not a warning about the site itself.
Cookies and trackers are part of how the web works, but you have more control than you think. Choose necessary-only cookies, block third-party tracking, review permissions and extensions, and understand what private browsing really does.
