How to delete cookies on your Mac the right way

3 min read

When it comes to the web, a cookie is simply a bit of data websites store to make return visits easier. When you shop online and it remembers your address, that’s a cookie at work.

Cookies aren’t always bad. They’re stored on your device, so your information is not ‘out there’ in the wild for hackers to grab (at least via cookies). They also make browsing the web simpler, as you don’t need to re-enter information each time you visit.

But cookies also take up space on your device, and are readable. Many people like to clear cookies routinely, which we advocate. In this article we’ll show you how to clear cookies on Chrome, clear cookies on Safari and Firefox, and the best app to ensure your cookies are totally gone.

The easiest way to clear cookies

If you want to quickly and effectively clear cookies on all your browsers, CleanMyMac X is the way to go. It makes quick work of clearing cookies across all the browsers you use. Here’s how to clear cookies with CleanMyMac X:

  1. Open CleanMyMac X
  2. Select ‘Privacy’ from the left hand side of the window

    CleanMyMac X Privacy Scan

  3. Select ‘Scan’ at the bottom of the screen 
  4. Close any browsers you may be using
  5. Select the browser you want to clear cookies from
  6. Select ‘cookies’

    Clean up cookies from Chrome

  7. If you’d like to delete specific cookies, use the drop-down menu in the cookies field to show individual cookies and select those you want to delete
  8. Once you’ve selected specific cookies or all cookies to delete, select ‘Remove’ at the bottom of the window.

And that’s it! Now all your cookies are gone, and you can go back to browsing the web on your computer.

How to delete cookies on Chrome manually

Deleting cookies on Chrome is not quite as simple as you’d want it to be. Google hides it deep in its settings menu, buried behind a few sub-categories. It’s not impossible, or hard, just not as fluid an experience as we’d like.

Here’s how to erase cookies on Chrome:

  1. Open Chrome
  2. Go to the ‘more’ menu on the top right of the screen.
  3. Select ‘Settings’

    Chrome Settings

  4. Scroll down until you see the ‘Advanced’ sub-menu
  5. Select ‘Privacy and Security’
  6. Select ‘Clear Browsing Data’

  7. Ensure your settings are correct. You can choose to delete all your data, and your entire history, or just cookies. It’s pleasantly granular; once you decide what you’d like to erase, select ‘Clear Data’ 

Clear cookies on Safari manually

  1. Open Safari
  2. From the menu bar, select Safari > Preferences [cookies10]
  3. Select ‘Privacy’
  4. Select ‘Manage Website Data’ under ‘Cookies and website data’ Manage website data in Safari browser
  5. Choose the cookies you’d like to delete, or ‘remove all’

And that’s it! Safari makes it delightfully simple, and allows you the option to preemptively block all cookies from being captured. That’s a handy feature, but will make browsing the web less simple.

How to clear cookies on Firefox manually

Firefox has a lot more granular control for deleting cookies. You can opt to delete cookies for a single website, disable cookies, or delete all cookies. Here, we’ll focus on how to delete all cookies Firefox:

  1. Open Firefox

  2. Open the ‘settings’ menu on the top right

  3. Select ‘Preferences’ 

    Firefox preferences

  4. In the new window, select ‘Privacy & Security’ 

  5. Scroll down until you see ‘Cookies and Site Data.’ Select ‘Clear data’

  6. Select ‘clear.’ In the popup, select ‘clear now’ to confirm you want to proceed.’ 

    Clear cookies in Firefox browser

That’s it! Now all of your cookies are clear from Firefox. It’s a lot simpler than Chrome, but not quite as seamless as Safari.


Deleting cookies on your computer shouldn’t be difficult. With privacy becoming a concern shared by more users daily, you would think the companies who make browsers would ensure deleting cookies was simple.

Unfortunately, none really make it simple. Safari is far and away the easiest to manage, but it’s still imperfect. Firefox and Chrome both let you erase cookies, but it’s buried in a settings menu.

This is why we prefer CleanMyMac X. It has a much better interface, and doesn’t try to dissuade you from accessing the option to delete cookies. It keeps everything front and center. CleanMyMac X also allows you to delete cookies from multiple browsers at once, which is great for those who prefer one browser but need to use a different browser for some purposes.

CleanMyMac X also takes privacy and upkeep to the limit. It helps you manage the health and cleanliness of your digital life like no other app can with options for managing your mail attachments, trash bins, browser extensions, a malware checker, and the ability to run a full system diagnostic check to ensure your Mac is running at peak performance.
