Have you ever wondered why ads seem to follow you from one website to another? That is cookies at work. Small text files stored in your browser track your activity, remember your preferences, and sometimes share data with third parties. If you value your privacy, knowing how to turn off cookies is a useful skill.
This guide walks you through exactly how to disable cookies in the most popular web browsers. Whether you use Chrome, Firefox, Safari, Edge, Opera, Brave, or Samsung Internet, you will find clear steps here.
Before jumping into the steps, it helps to understand what cookies actually do and why turning them off might affect certain websites. Some pages rely on cookies for basic functions like keeping you logged in. Disabling them fully could change how those sites behave. With that said, let us get started.
Browser cookies are tiny data files websites store on your device. They serve different purposes depending on their type and origin.
These come directly from the website you visit. They remember your login details, language settings, and shopping cart items. Most websites need these to function properly. Without them, you would have to log in every time you visit a page.
These come from external domains, usually advertisers or analytics providers. They track your activity across multiple websites. This is why you see the same product advertised on different sites after browsing once. Third-party cookies are the main privacy concern for most users.
Disabling cookies limits how much data websites collect about you. It reduces targeted advertising and stops cross-site tracking. For users who care about online privacy, this is a straightforward step. However, blocking all cookies can cause some websites to break or function poorly. The best approach is understanding your options in each browser.
Google Chrome is the most widely used browser globally. Here is how to disable cookies in Chrome on both desktop and mobile.
Open Chrome and click the three-dot menu in the top-right corner. Select Settings from the dropdown. On the left panel, click Privacy and Security. Then click Third-party cookies. You will see options to block third-party cookies or block all cookies. Select Block all cookies if you want full protection. Chrome will warn you that some sites may not work properly.
Open Chrome on your Android device. Tap the three-dot menu and go to Settings. Tap Privacy and Security, then tap Third-party cookies. Choose Block all cookies. This immediately stops websites from storing cookie data on your phone.
Chrome on iOS follows Apple’s privacy framework. Open Chrome, tap the three-dot menu, and go to Settings. Navigate to Privacy and Security and adjust your cookie preferences. Note that iOS already blocks many third-party cookies by default through its system-level protections.
Firefox offers strong privacy controls built right into the browser. Disabling cookies here takes just a few clicks.
Open Firefox and click the three-line menu in the top-right corner. Select Settings and go to Privacy & Security. Under Enhanced Tracking Protection, choose Strict. This blocks most third-party cookies, tracking content, cryptominers, and fingerprinters automatically. It is the quickest way to improve privacy.
If you want to block all cookies entirely, select Custom under Enhanced Tracking Protection. From the Cookies dropdown, choose All Cookies. Firefox will warn you that this setting may cause websites to break. This gives you complete control over what gets stored.
Scroll down in Privacy & Security settings. Enable Delete cookies and site data when Firefox is closed. This approach lets cookies work during your session but removes them automatically when you close the browser. It is a balanced option for users who want convenience without long-term tracking.
Apple’s Safari browser already blocks third-party cookies by default. But you can go further if you want complete cookie blocking.
Open Safari and click Safari in the menu bar. Select Settings (or Preferences on older versions). Go to the Privacy tab. Tick the box next to Block all cookies. Safari will ask you to confirm since this may prevent some websites from working correctly.
Go to your device Settings app. Scroll down and tap Safari. Under Privacy & Security, toggle on Block All Cookies. A confirmation prompt will appear. Tap Block All to confirm. This stops all websites from storing cookies on your iOS device.
Even without changing any settings, Safari uses Intelligent Tracking Prevention (ITP). This feature automatically limits cross-site tracking and restricts third-party cookies. For most users, Safari already provides solid privacy protection out of the box.
Microsoft Edge is built on the same engine as Chrome. The cookie settings are similar but located in different menus.
Open Edge and click the three-dot menu in the top-right corner. Select Settings, then click Cookies and site permissions on the left panel. Click Manage and delete cookies and site data. Toggle off Allow sites to save and read cookie data. This blocks all cookies in Edge immediately.
If you prefer a less restrictive approach, keep the main toggle on but enable Block third-party cookies. This stops tracking cookies from external domains while still letting first-party cookies function. Most users find this to be the ideal balance between privacy and usability.
Open Edge on your phone. Tap the three-dot menu and go to Settings. Select Privacy and security, then Cookies. Choose Block all cookies or Block third-party cookies depending on your preference. The mobile version mirrors the desktop settings closely.
Opera shares its core engine with Chrome, so the settings follow a similar structure.
Open Opera and click the three-line menu or the Opera icon in the top-left corner. Select Settings (or press Alt+P on Windows). Scroll down to Privacy and security. Click Site settings, then click Cookies and site data.
Under Cookies and site data, select Block all cookies. Opera will apply the change immediately. You can also choose to block only third-party cookies if you want websites to function normally while still reducing tracking.
Opera includes a free built-in VPN. When combined with cookie blocking, it adds an extra layer of privacy. Enable the VPN from Settings under Features. Using both features together helps prevent tracking through cookies and through your IP address.
Brave is built for privacy by default. It blocks third-party cookies automatically, but you can tighten the settings further.
Open Brave and click the three-line menu. Select Settings, then navigate to Privacy and security on the left panel. Click Cookies and other site data. You will see three options listed clearly.
Select Block all cookies for maximum privacy. Keep in mind that some websites may not load correctly with this setting.
Brave also offers Shields, a built-in feature that blocks ads, trackers, and cookie consent pop-ups. You can adjust Shields on a per-site basis by clicking the lion icon in the address bar. This gives you granular control without changing global settings.
Samsung Internet is the default browser on Samsung Galaxy devices. It has straightforward cookie settings.
Open Samsung Internet and tap the three-line menu at the bottom. Select Settings, then tap Privacy and security. Find the Accept cookies option and toggle it off. This stops all websites from storing cookies on your Samsung device.
If turning off all cookies causes issues, you can take a softer approach. Under Accept cookies, tap the option and disable only Allow third-party cookies. This keeps first-party cookies active for login sessions and preferences while blocking cross-site trackers.
To remove cookies already stored on your device, go to Settings and tap Personal browsing data. Select Cookies and site data, then tap Delete. This clears all stored cookie data and gives you a clean slate going forward.
Disabling cookies changes how websites interact with your browser. Here is what to expect after you make the switch.
Cookies store your login sessions. Without them, websites cannot remember that you have already signed in. You will need to enter your username and password each time you visit a site. This is the most noticeable change.
Certain websites rely on cookies for core functions. Shopping carts, form submissions, and personalised content may stop working. If a site breaks after you disable cookies, you can add it as an exception in your browser’s cookie policy settings.
Without third-party cookies, advertisers cannot track your browsing habits across websites. You will see fewer personalised ads. The ads you do see will be more generic and less tied to your recent searches or browsing activity.
Blocking all cookies is effective but can be inconvenient. A smarter approach is to block only third-party cookies. This stops cross-site tracking while keeping essential website functions intact. Most browsers offer this as a middle-ground setting. It protects your privacy without forcing you to log in repeatedly or deal with broken pages. For website owners looking to handle user consent properly, using a consent management platform helps manage cookie preferences transparently.
First-party cookies handle logins, language settings, and shopping carts. Blocking them breaks basic functionality. Third-party cookies handle tracking, retargeting, and cross-site analytics. Removing them improves privacy without disrupting your browsing experience.
Most modern browsers include additional privacy features like tracking prevention, fingerprint protection, and automatic cookie clearing. Using these alongside third-party cookie blocking gives you strong protection. Features like Google Consent Mode v2 also help websites respect your choices while still collecting consented data.
Even if you do not block all cookies, clearing them regularly is a good practice. Set your browser to delete cookies on close or clear them manually once a week. This limits the data that builds up over time and keeps your browsing history cleaner.
Here is a summary of where to find cookie settings in each browser covered in this guide.
Turning off cookies is one of the simplest steps you can take to protect your online privacy. Every major browser gives you the option to block cookies partially or completely. Whether you choose to disable all cookies or just third-party ones, the process takes less than a minute. Review your browser settings today and choose the level of privacy that works best for you.
If you run a website, giving visitors clear control over their cookie preferences is not optional anymore.

Set it up in minutes and stay on the right side of privacy regulations.
START FREE TODAYFirst-party cookies come from the website you are visiting directly. They store your login details, preferences, and session data. Third-party cookies come from external domains like advertisers and analytics platforms. They track your activity across multiple websites to build a profile of your browsing habits for targeted advertising purposes.
Disabling cookies significantly reduces tracking, but it does not eliminate it entirely. Websites can still use other methods like browser fingerprinting, pixel tracking, and IP-based identification. Combining cookie blocking with privacy-focused browser features, a VPN, and regular data clearing provides stronger overall protection against various tracking techniques.
Most browsers allow you to add exceptions for individual websites. In Chrome, Firefox, Edge, and Brave, you can go to the cookie settings and add specific URLs to a block list or allow list. This lets you block cookies on untrusted sites while keeping them active on websites you use regularly.
Cookies themselves are tiny files and have minimal impact on browser speed. However, a large number of accumulated cookies and cached site data can slow down page loading over time. Clearing cookies regularly helps maintain browser performance, especially if you visit many different websites throughout the day.
Accepting first-party cookies from trusted websites is generally safe. They are needed for basic functionality like staying logged in. However, accepting third-party cookies from every website increases your exposure to cross-site tracking and data collection. It is better to block third-party cookies by default and only allow them when necessary.
Clearing cookies once a week is a good practice for most users. If you visit many websites daily, consider clearing them more frequently or setting your browser to auto-delete cookies when it closes. Regular clearing removes stored tracking data and reduces the amount of personal information retained by websites.
Mobile browsers use the same cookie technology as desktop versions. However, mobile operating systems like iOS add extra privacy layers. Safari on iPhone blocks third-party cookies by default. Chrome and other browsers on Android follow their desktop settings closely but may include additional mobile-specific privacy features.
Saved passwords stored in your browser’s password manager remain unaffected when you disable cookies. Cookies and saved passwords are separate features. However, without cookies, websites cannot maintain your active login session, so you will need to enter your saved password each time you visit, even if the browser auto-fills it.
Under privacy regulations like GDPR and CCPA, websites must give users a genuine choice to accept or reject non-essential cookies. Some websites use cookie walls that limit access unless cookies are accepted. However, essential cookies required for basic site functionality can be placed without explicit consent in most jurisdictions.
Private or incognito mode does not block cookies during your browsing session. Websites still place cookies while you browse. The difference is that all cookies are automatically deleted when you close the private window. It provides temporary privacy but does not prevent tracking while the session is active.
