What cookies are and why you might want to clear them
Cookies are small files that websites store on your computer to remember information about you. When you visit a website, it may save a cookie that tracks what you looked at, keeps you logged in, or remembers your preferences. Most cookies are harmless, but clearing them can speed up your browser, free up storage space, and remove tracking data that websites have collected about your browsing habits.
You do not need to clear cookies often. Many people clear them once a month or when they notice their browser running slowly. If you are selling your computer, switching users, or concerned about privacy, clearing cookies is a straightforward step that takes less than a minute.
Key Takeaways
- Clearing cookies removes stored data from websites but does not delete your browsing history, passwords, or downloaded files unless you choose those options too.
- The process differs slightly between browsers: Chrome, Firefox, Safari, and Edge all have a dedicated "Clear browsing data" or "Clear cookies" menu.
- You can clear all cookies at once or set your browser to delete them automatically when you close it.
- Clearing cookies may log you out of websites you visit regularly, so you may need to sign in again.
How to clear cookies in Google Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings from the menu, then click Privacy and security in the left sidebar. Choose Clear browsing data.
A window will appear with several options. Make sure the time range at the top is set to All time if you want to remove all cookies, or select a specific date range. Under "Cookies and other site data," check the box next to that option. You can leave other boxes unchecked if you only want to remove cookies. Click the blue Clear data button at the bottom right. Chrome will clear the cookies and close the window.
How to clear cookies in Mozilla Firefox
Open Firefox and click the three horizontal lines (hamburger menu) in the top right corner. Select Settings, then click Privacy & Security in the left sidebar. Scroll down to the Cookies and Site Data section.
You will see a button labeled Clear Data. Click it, and a small window will pop up. Make sure Cookies and Site Data is checked. The time range defaults to "Everything," which removes all cookies. Click Clear to finish. Firefox will clear the cookies when ready.
How to clear cookies in Safari
Open Safari and click Safari in the menu bar at the top of the screen. Select Settings (or Preferences on older Macs), then click the Privacy tab. Click the button labeled Manage Website Data.
A list of websites and their stored data will appear. To remove all cookies at once, click Remove All at the bottom right. To remove cookies from specific websites, select them from the list and click Remove. Click Done when finished.
How to clear cookies in Microsoft Edge
Open Edge and click the three dots in the top right corner. Select Settings, then click Privacy, search, and services in the left sidebar. Under Clear browsing data, click Choose what to clear.
A window will open. Set the time range to All time at the top if you want to remove all cookies. Check the box next to Cookies and other site data. Click the blue Clear now button. Edge will remove the cookies and close the window.
Set your browser to delete cookies automatically
Instead of clearing cookies manually, you can configure your browser to delete them automatically when you close it. In Chrome, go to Settings > Privacy and security > Cookies and other site data, then toggle on Delete cookies and site data when you quit Chrome. In Firefox, go to Settings > Privacy & Security > Cookies and Site Data, then select Delete cookies and site data when Firefox is closed. In Safari, go to Privacy > Manage Website Data and click Remove All regularly, or use the Privacy settings to block cookies from third-party websites. In Edge, go to Settings > Privacy, search, and services and toggle on Clear browsing data > Choose what to clear every time you close the browser.
This approach keeps your computer cleaner without requiring you to remember to clear cookies manually. The downside is that you will be logged out of most websites each time you close your browser.
What happens when you clear cookies
When you clear cookies, you will be logged out of most websites. The next time you visit a site where you have an account, you will need to sign in again. Websites will no longer remember your preferences, such as language settings or items in your shopping cart. Your browsing history, passwords saved in your browser, and downloaded files are not affected unless you specifically choose to delete those as well.
Some websites may load slightly slower the first time you visit them after clearing cookies, because they have to rebuild your preferences from scratch. This slowdown is temporary and usually unnoticeable.
Frequently Asked Questions
Will clearing cookies delete my passwords?
No. Cookies and saved passwords are stored separately. When you clear cookies, your browser will ask you to sign in again, but your saved passwords remain unless you specifically choose to delete them in the password settings.
Can I clear cookies from just one website?
Yes. In Chrome, Firefox, and Edge, you can visit a website, click the lock icon or site information icon in the address bar, and select the option to clear cookies for that site only. In Safari, use the Manage Website Data window to select individual sites and click Remove.
What is the difference between clearing cookies and clearing browsing history?
Browsing history is a list of websites you have visited. Cookies are files websites store on your computer. Clearing history removes the list; clearing cookies removes the stored files. You can do either one independently.
Do I need to clear cookies regularly?
Not necessarily. Most people do not need to clear cookies more than once a month. If your browser feels slow or you are concerned about privacy, clearing cookies can help. If you do not notice any problems, there is no urgent reason to clear them.
What if a website says my cookies are disabled?
This means the website requires cookies to function, and your browser settings are blocking them. Check your browser settings to make sure cookies are enabled. You may have accidentally turned off cookie storage, or a browser extension may be blocking them.
