What disabling cookies actually does
Disabling cookies stops websites from storing small files on your device that track your browsing, remember your login information, and follow you across the internet. When you turn off cookies, websites can no longer build a profile of your interests or recognize you when you return.
The trade-off is real: many websites will stop working properly. You'll have to log in every single time you visit, shopping carts will empty between sessions, and some pages won't load at all. Some news sites and streaming services will block you entirely if cookies are disabled. Most people find a middle ground — blocking third-party cookies (the tracking kind) while allowing first-party cookies (the ones that make websites function).
The steps below cover the major browsers. The process takes two to five minutes per browser, and you can change your mind anytime by reversing these steps.
Key Takeaways
- Disabling all cookies breaks many websites, so blocking only third-party cookies is usually the better choice for privacy without breaking functionality.
- Each browser stores cookie settings in a different location, but all are found in Settings or Preferences under Privacy or Security.
- You can set different rules for different websites — allow cookies on sites you trust, block them everywhere else.
- Clearing your existing cookies removes the tracking data already stored, but new cookies will be created unless you disable them going forward.
Disable cookies in Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings, then click Privacy and security in the left sidebar. Click Cookies and other site data.
You'll see three options. Allow all cookies is the default. To block third-party cookies (the tracking kind), select Block third-party cookies. To block all cookies, select Block all cookies — but expect many sites to break. If you choose to block all cookies, Chrome will warn you that some sites won't work.
To clear cookies you already have stored, stay in this same menu and click Clear browsing data. Make sure Cookies and other site data is checked, then click Clear data. This removes existing tracking files but doesn't prevent new ones from being created unless you've already changed your cookie setting above.
Disable cookies in Firefox
Open Firefox and click the three horizontal lines in the top right corner. Select Settings, then click Privacy & Security in the left sidebar. Scroll down to the Cookies and Site Data section.
Check the box next to Delete cookies and site data when Firefox is closed. This automatically clears all cookies every time you close the browser, which is the strongest privacy option without breaking websites. If you want more control, click Manage Exceptions to allow cookies on specific sites you trust while blocking them everywhere else.
To clear cookies right now, click Clear Data in the same section. Make sure Cookies and Site Data is checked, then click Clear. Firefox will remove all stored cookies immediately.
Disable cookies in Safari
Open Safari and click Safari in the top menu bar. Select Settings (or Preferences on older Macs), then click the Privacy tab.
Look for the section labeled Cookies and website data. Select Block all cookies to prevent all cookies from being stored. Safari also offers Allow only websites I visit, which blocks third-party tracking cookies while allowing first-party cookies that make websites work. This middle option is usually the best choice.
To clear existing cookies, click Manage Website Data in the same Privacy tab. You'll see a list of all websites that have stored data on your device. Click Remove All to delete everything, or select specific sites and click Remove.
Disable cookies in Edge
Open Microsoft Edge and click the three dots in the top right corner. Select Settings, then click Privacy, search, and services in the left sidebar. Scroll down to Clear browsing data and click Choose what to clear.
Check the box next to Cookies and other site data, then click Clear now. This removes cookies you already have. To prevent new cookies from being created, scroll back up in the same Privacy menu and find Cookies and other site data. Select Block all cookies to stop all cookies, or Block third-party cookies to allow websites to function while blocking trackers.
Allow cookies on specific websites you trust
Most browsers let you create exceptions — sites where cookies are allowed even though you've blocked them everywhere else. This is useful for banking sites, email, or shopping sites where you want to stay logged in.
In Chrome, go to Settings > Privacy and security > Cookies and other site data > Sites that can always use cookies. Click Add and type the website address. In Firefox, click Manage Exceptions in the Cookies and Site Data section and add the address there. In Safari, click Manage Website Data and uncheck sites you want to allow. In Edge, go to Settings > Privacy > Cookies and other site data > Manage exceptions and add the site.
Use this feature sparingly — the more exceptions you create, the more tracking data you're allowing to be stored. Stick to sites where you genuinely need to stay logged in or where functionality is broken without cookies.
What to do if a website stops working
If you've disabled all cookies and a website won't load or won't let you log in, you have three options. The quickest is to temporarily allow cookies just for that site using the exception method above. The second is to switch to a private or incognito window, which doesn't store cookies between sessions. The third is to use a different browser where you haven't disabled cookies.
If a website refuses to work even with cookies allowed, the site itself may have a technical problem, or it may require a feature your browser doesn't support. Contact the website's support team to report the issue. Most major websites test their functionality with cookies disabled, so this is usually a sign of a genuine bug rather than a privacy setting conflict.
Frequently Asked Questions
Will disabling cookies make me anonymous online?
No. Disabling cookies stops one tracking method, but websites can still identify you through your IP address, browser fingerprinting, and login accounts. Cookies are just one piece of how you're tracked. Disabling them is a useful privacy step, but it's not the same as being anonymous.
Do I need to disable cookies if I use private browsing?
Private or incognito mode already clears cookies when you close the window, so disabling cookies in your regular settings won't affect private browsing. If you use private mode most of the time, you may not need to disable cookies in your main browser settings.
Will disabling cookies slow down my internet?
No. Cookies are tiny files — usually a few kilobytes each — so they have no meaningful impact on speed. Disabling them won't make websites load faster or slower. The only performance change you might notice is that websites take slightly longer to load because they can't remember your preferences and have to ask for them again.
Can websites tell if I have cookies disabled?
Yes, websites can detect whether you accept cookies, and some will show you a message or block access if you refuse. This is why some news sites and streaming services won't work with cookies disabled — they use cookies to track subscriptions and prevent unauthorized sharing.
Should I clear cookies before or after disabling them?
Clear them after you've changed your cookie setting. If you clear first and then disable, you've done the job in the right order — you've removed old tracking data and prevented new tracking data from being created. If you disable first and then clear, you'll still get the same result, just in reverse order.
