What disabling cookies does and doesn't do
Disabling cookies stops websites from storing small files on your device that track your browsing, remember your login information, and build a profile of your interests. When you disable cookies, websites cannot recognize you on repeat visits, shopping carts empty between sessions, and data brokers lose one major tool for following you across the internet.
Disabling cookies is not the same as removing your information from data broker websites. Data brokers collect information from public records, purchase history, and other sources — they do not need cookies to know about you. Disabling cookies prevents them from tracking your future activity, but it does not erase what they already have. You still need to contact data brokers directly to request removal.
Cookies come in two types: session cookies disappear when you close your browser, while persistent cookies
Key Takeaways
- Disabling cookies stops websites from tracking your browsing and building profiles about you, but does not remove information data brokers already collected.
- Each browser has its own cookie settings — you must disable cookies separately in Chrome, Firefox, Safari, and Edge.
- Disabling all cookies may break some websites, so you can instead block third-party cookies, which handle most tracking without breaking core website functions.
- Clearing your cookies regularly removes tracking files already on your device, but disabling cookies prevents new ones from being stored.
Disable cookies in Google Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings from the menu. On the left side, click Privacy and security, then click Cookies and other site data.
You will see three options. Allow all cookies is the default. Block third-party cookies in Incognito blocks tracking cookies only when you use Incognito mode. Block all cookies disables cookies entirely. Choose Block all cookies if you want maximum privacy. If websites stop working, return here and select Block third-party cookies in Incognito instead — this blocks most tracking while keeping websites functional.
To clear cookies you already have stored, stay in the same Privacy and security section and click Clear browsing data. Make sure Cookies and other site data is checked, then click Clear data.
Disable cookies in Mozilla Firefox
Open Firefox and click the three horizontal lines in the top right corner. Select Settings. On the left, click Privacy & Security. Under Cookies and Site Data, you will see a checkbox that says Delete cookies and site data when Firefox is closed. Check this box to remove all cookies automatically each time you close the browser.
For more control, look for the section labeled Enhanced Tracking Protection just above the cookies section. Click Custom and check the boxes next to Cookies and Tracking content. This blocks most tracking cookies while allowing some cookies that websites need to function.
To clear cookies when ready, press Ctrl+Shift+Delete on Windows or Command+Shift+Delete on Mac. Check Cookies and click Clear Now.
Disable cookies in Safari
Open Safari and click Safari in the top menu bar. Select Settings (or Preferences on older versions). Click the Privacy tab. Under Cookies and website data, select Never allow to block all cookies, or Allow only websites I visit to allow cookies only from sites you actively navigate to — this blocks most tracking.
To clear cookies you already have, go back to the Privacy tab and click Manage Website Data. Click Remove All to delete all stored cookies and site data.
Disable cookies in Microsoft Edge
Open Edge and click the three dots in the top right corner. Select Settings. On the left, click Privacy, search, and services. Under Cookies and other site data, you will see a dropdown menu. Select Block all cookies for maximum privacy, or Block third-party cookies to allow cookies that websites need while blocking tracking cookies.
To clear existing cookies, stay in Privacy, search, and services and scroll down to Clear browsing data. Click Choose what to clear. Check Cookies and other site data and click Clear now.
What to expect after disabling cookies
After you disable cookies, websites will not remember you. You will need to log in again each time you visit a site that requires an account. Shopping carts will empty when you close your browser. Some websites may not load properly or may ask you repeatedly to accept cookies.
If a website stops working, you have two options: add that specific website to an exception list (most browsers allow this), or switch to blocking only third-party cookies instead of all cookies. Third-party cookies handle most tracking and are the main tool data brokers use to follow you across websites. Blocking them alone solves most privacy concerns without breaking functionality.
Disabling cookies does not hide your internet activity from your internet service provider or from the websites you visit directly. It only prevents cookies from tracking you across multiple websites and building a profile of your interests.
Combine cookie blocking with other privacy steps
Disabling cookies works best alongside other privacy measures. Use a private or incognito browsing mode when you do not want any browsing history saved. Consider using a VPN (virtual private network) to hide your IP address from websites and your internet service provider. Enable Do Not Track in your browser settings — most browsers have this option in privacy settings, though not all websites honor it.
If you are trying to remove your information from data brokers, disabling cookies prevents them from collecting new data about you going forward, but you still need to contact each data broker individually to request removal of information they already have. Some data brokers have online removal forms; others require a phone call or letter. Check the data broker's website for their removal process.
Frequently Asked Questions
Will disabling cookies make websites unsafe?
No. Cookies themselves are not a security risk — they are just small text files. Disabling them does not make you safer from viruses or malware. It only stops websites from tracking your activity and building profiles about you. Some websites may ask you to log in more often, but that is an inconvenience, not a security problem.
Can I disable cookies for some websites but not others?
Yes. In most browsers, you can add websites to an exception list. In Chrome, go to Settings > Privacy and security > Cookies and other site data > Sites that can always use cookies and add the website address. Firefox, Safari, and Edge have similar exception options in their cookie settings.
Do I need to disable cookies if I use private browsing mode?
Private or incognito mode deletes cookies when you close the window, but it does not prevent websites from setting cookies while you are browsing. Disabling cookies in your browser settings is more thorough because it stops cookies from being stored in the first place, even in private mode.
Will disabling cookies stop data brokers from tracking me?
Disabling cookies stops data brokers from using cookies to follow you across websites, but they collect information from many other sources — public records, purchase history, and data they buy from other companies. Disabling cookies prevents new tracking but does not remove information they already have. You must contact data brokers directly to request removal.
What is the difference between clearing cookies and disabling them?
Clearing cookies removes the tracking files already stored on your device. Disabling cookies prevents new tracking files from being stored. Clearing cookies is a one-time action; disabling cookies is an ongoing setting. For best privacy, do both — disable cookies in your settings and clear existing cookies regularly.
