How to Block Cookies in Chrome, Safari, & More

This How.com.vn article will teach you how to block cookies in Chrome, Safari, Firefox, Edge, and DuckDuckGo web browsers. Cookies are usually helpful—they can make it possible for you to log into websites and use online shopping carts. Other cookies follow you around the web, silently collecting data about your browsing habits. Since disabling all cookies can make it hard to use your favorite websites, we’ll also show you how to keep the helpful cookies and block the ones that track you.

Open Chrome on your Android. If you're using Chrome on an iPhone or iPad, you'll need to leave cookies enabled. There is no way to disable them.^{[1]XResearch source}

- Alternatively, if you just want to disable third-party cookies, including the kind that track you on the internet, go back to the Site settings menu, select Third-party cookies, and select one of these options:
  - Block third-party cookies in Incognito: This option leaves cookies on but disables them when you browse an Incognito window. If you choose this option, you'll keep the normal benefits of cookies, and block tracking cookies when not in Incognito mode.
  - Block third-party cookies: This allows websites to save cookies used to improve your browsing experience (such as those that keep you signed in or manage an online shopping cart) while blocking invasive tracking cookies. This is the best option for blocking cookies without losing convenient website features.

- Cross-site tracking cookies: This option blocks cookies that track you across different websites, including those used by social media websites to tailor your advertising. This is the default option and shouldn't break most websites.
- Cross-site tracking cookies, and isolate other cross-site cookies: This option blocks all tracking cookies, but allows some third-party cookies that can help you stay logged in to websites.
- Cookies from unvisited websites: This option only blocks cookies from websites you've never accessed.
- All cross-site cookies (may cause websites to break): This option blocks all cookies from sites other than the ones used just for the sites you visit. You'll still be able to use a website's shopping cart, but you won't be able to use social media accounts to log in. Some websites could break, but no third parties could track what you do.
- All cookies (will cause websites to break): This option blocks all types of cookies, including the ones that let you sign in to websites and shop online. This is the most severe option.

DuckDuckGo Browser

Because the cookies that can track and harm your computer, phone, and tablet are blocked automatically, you don't need to block cookies yourself. There is no way to block all cookies with DuckDuckGo, as these settings are not customizable.
