Where to find and delete cookies in Safari, Chrome, and Firefox
Cookies are small files your browser stores when you visit websites. They remember your login information, shopping cart contents, and browsing preferences. Over time, they accumulate and can slow down your browser or raise privacy concerns. Deleting them is straightforward on a MacBook Pro and takes less than a minute in any major browser.
The steps differ slightly depending which browser you use, but all three major options — Safari, Chrome, and Firefox — put the delete function in the same general location: the browser's settings or preferences menu. You do not need any special tools or third-party software.
Key Takeaways
- Safari stores the cookie deletion option under Safari menu > Settings > Privacy, where you can delete all cookies or choose a date range.
- Chrome and Firefox both hide cookie deletion in their settings under Privacy or History, accessible through the menu button or keyboard shortcut.
- You can delete cookies when ready or set your browser to delete them automatically every time you close it.
- Deleting cookies will log you out of most websites and remove saved passwords unless you specifically protect them during deletion.
- Clearing cookies does not delete your browsing history, saved passwords, or autofill data unless you choose those options too.
Delete cookies in Safari
Open Safari and click the Safari menu in the top left corner of your screen. Select Settings (or Preferences if you are using an older macOS version). Click the Privacy tab at the top.
You will see a section labeled Cookies and website data. Click the Manage Website Data button to see a list of every website that has stored cookies on your Mac. You can delete cookies from individual websites by selecting them and clicking Remove, or click Remove All to delete everything at once. Click Done when finished.
If you want Safari to delete cookies automatically, stay in the Privacy tab and look for the dropdown menu that says Cookies and website data. Change it from Always accept to Never or From visited. This prevents new cookies from being stored, though it may break some websites that require them to function.
Delete cookies in Chrome
Open Chrome and click the three vertical dots (menu button) in the top right corner. Select Settings. Click Privacy and security in the left sidebar, then click Clear browsing data.
A window will pop up with several options. Make sure Cookies and other site data is checked. At the top, choose your time range: All time deletes everything, while Last hour, Last 24 hours, or Last 7 days let you delete only recent cookies. Click Clear data.
To delete cookies automatically when you close Chrome, go back to Settings > Privacy and security and toggle on Clear cookies and site data when you quit Chrome. This logs you out of websites each time you close the browser.
Delete cookies in Firefox
Open Firefox and click the hamburger menu (three horizontal lines) in the top right corner. Select Settings. Click Privacy & Security in the left sidebar.
Scroll down to the section labeled Cookies and Site Data. Click the Clear Data button. A window appears with two checkboxes: make sure Cookies and Site Data is checked. You can also check Cached Web Content if you want to free up storage space. Click Clear.
To have Firefox delete cookies automatically, stay in Privacy & Security and look for the dropdown under Cookies and Site Data. Select Delete cookies and site data when Firefox is closed. Firefox will then clear all cookies every time you quit the process.
What happens when you delete cookies
Deleting cookies will log you out of most websites. The next time you visit Facebook, Gmail, your bank, or any other site where you were logged in, you will need to enter your username and password again. This is the most noticeable change you will experience.
Websites may also load slightly slower the first time you visit them after deleting cookies, because they no longer have your preferences stored. A news site might forget which articles you have read, or an online store might stop showing you personalized recommendations. These settings rebuild as you browse.
Deleting cookies does not delete your saved passwords, browsing history, or autofill information unless you specifically check those boxes during the deletion process. If you want to keep your passwords but delete cookies, make sure only the cookies checkbox is selected.
When to delete cookies and when to keep them
Delete cookies if you share your MacBook Pro with other people and want to prevent them from accessing your accounts, or if you are concerned about websites tracking your browsing behavior. Deleting them regularly — once a month or once a quarter — is a reasonable privacy practice for most people.
Keep cookies if you want to stay logged into your accounts and have websites remember your preferences. The trade-off is that advertisers and analytics companies can use cookies to track which sites you visit. If you want a middle ground, delete cookies monthly but let your browser save new ones as you browse.
If a website stops working correctly after you delete cookies, try clearing your browser cache as well. Some sites store important data in both places. You can clear the cache through the same menu where you delete cookies — it is usually a checkbox labeled Cached images and files or Cached Web Content.
Frequently Asked Questions
Will deleting cookies delete my saved passwords?
No, unless you specifically check the box for saved passwords during deletion. Cookies and passwords are stored separately. You can delete one without affecting the other. If you want to keep your passwords but remove cookies, uncheck the passwords option before clicking delete.
Can I delete cookies from just one website?
Yes. In Safari, click Safari > Settings > Privacy > Manage Website Data, find the website in the list, select it, and click Remove. In Chrome and Firefox, you can block cookies from specific sites through Settings > Privacy, but deleting cookies from individual sites is less straightforward — you may need to delete all cookies and then log back into the sites you want to keep.
What is the difference between deleting cookies and clearing browsing history?
Cookies are small data files websites store on your computer. Browsing history is a list of websites you have visited. Deleting cookies does not erase your history, and deleting history does not remove cookies. You can delete one without affecting the other by unchecking the option you do not want during the deletion process.
Do I need to delete cookies regularly?
No, but many people delete them monthly or quarterly for privacy reasons. Cookies do not harm your computer or slow it down significantly. Delete them if you share your Mac with others, if you are concerned about tracking, or if a website is not working correctly. Otherwise, it is optional.
Why does a website ask me to accept cookies when I visit?
Websites show cookie notices because of privacy laws like GDPR in Europe and CCPA in California. These laws require websites to tell you they are storing data. Accepting cookies lets the site function normally and remember your preferences. Rejecting them may limit site features, but you can still browse most websites without accepting.
