Google’s Chrome is, by most measures, the most popular browser in use. That being said, it also has a perception problem as far as security is concerned, causing privacy-concerned users to shake the Chrome habit. If you don’t have any intention of moving away from Chrome anytime soon, here are some tips to help you maximize your privacy.
Chrome has tools for blocking first-party cookies (which are used to store your preferences for a particular site) as well as third-party tracking cookies (which follow your online activity across sites). Some of these tools need to be enabled manually, and we’ve included instructions on how to do that, along with steps on how to delete cookies already stored by your browser. We also address how Google plans to prevent fingerprinting — a form of tracking that uses data about your system configuration to identify you.
There are also plenty of extensions available in the Chrome Web Store if you’d like to protect your privacy beyond Chrome’s built-in tools.
Deal with trackers
Version 79 of Chrome, which came out last December, concentrated mostly on enhancing password security. In Chrome 80, which began rolling out on February 4th, Google is gradually implementing a new system for sorting and blocking cookies. It will allow all first-party cookies, but third-party cookies will have to include a specific same-site setting that ensures they are being accessed from secure connections. (You can update to the Chrome 80 manually by going to Help -> About Google Chrome. However, be aware that this feature may take a while to be fully implemented.)

Adjust your tracking settings
Meanwhile, you can still manually block cookies in Chrome:
- Go to “Settings” (by clicking the three dots in the upper-right corner next to the URL bar). Scroll down and click on “Advanced” at the bottom of the screen or in the menu bar on the left.
- Find the “Privacy and security” section, and then click on “Site settings” -> “Cookies and site data.”
- To block only third-party cookies, toggle “Block third-party cookies” on. To block all cookies, toggle the “Allow sites to save and read cookie data” to off.
Once you’ve blocked third-party cookies in your settings, a cookie icon will pop up on the right side of your address bar when Chrome is blocking cookies. You can click on that icon to see what cookies are allowed and blocked by each site and choose to block or allow individual cookies. Here’s how:
- Click on the icon, and a small window will open
- You can, at this point, allow cookies from this site or continue to block cookies. Click on “Done” to save your settings.
- To view which cookies are being blocked, click “Show cookies and other site data” at the bottom of that window. You can toggle between seeing the “Allowed” and “Blocked” cookies.
- Click on the site name; you’ll see either “Block” or “Allow” at the bottom of the window, allowing you to block or permit cookies from that site. If you click on the arrows next to the site names, you can see the individual cookies and can block or allow them as well.
- When you click on an individual cookie’s name, you’ll also see its domain, when it was created, and when it expires.
Clean up your cookies
Chrome does allow you to automatically clear out your cookies and other data when you exit the browser.
- Go to the “Cookies and site data” page as described above
- Toggle on “Clear cookies and site data when you quit Chrome”
Want to see a list of all the cookies currently stored by your browser?
- In the “Cookies and site data” page, click on “See all cookies and site data.” You can delete cookies by site by clicking on the trash icon next to each site name, or you can delete them all by clicking “Remove all.”
- If you click on the site name, you’ll be able to see the individual cookies left by that site. Click on the arrow for more information about the cookie, and click on the “X” to delete it.
If you want to clear a range of your data from the browser:
- Go to “Settings” -> “Privacy and Security” -> “Clear browsing data”
- A window will open up with two viewing options: “Basic” and “Advanced.” The former allows you to clear out your cookies, browsing history and caches; the latter gives you the chance to delete all of those items along with other types of data, such as your download history, passwords, and autofill form data.
- At the top of the box, select an option from the drop-down menu next to “Time range.” You can clear anything from the last hour’s worth to all of the data that’s been collected.
- In either view, make sure the categories of data you want to delete are selected, and then click “Clear data”
Fingerprinting and ad-blocking
Google has proposed a number of fingerprinting protections, which it says it plans to implement later this year. Among the proposed steps is a strategy, which involves restricting the number of requests that can be made for user information so as not to allow for the collection of enough data to identify individual users.
