How to Delete Cookies on Mac? – Guide for: Safari, Chrome & Firefox

Here’s a handy guide on how to delete cookies on Mac. Removing cookies is naturally directly connected to the browser you use. To make it easier, we'll go over each and show you how to clean up cookies from the three most popular browsers: Firefox, Safari, and Chrome.

Before we plunge into details, I should say there’s an easier (and a considerably faster) way to cleaning cookies, with an app like CleanMyMac X. Try it, it really saves time. Now, let’s figure out why you want them deleted.

What are internet cookies?

Cookies are parts of information (tiny pieces of specific data) sent from websites you visit to your browser. Cookies identify you and help these websites recognize you when you return.

Why are cookies important? 

These pieces contain information about your online behavior, which allows websites to tailor your browsing experience to your preferences. Cookies also allow you to stay logged in on the website even if you close the tab.

As web servers have no memory to store cookies, they are instead saved to your Mac. Some of them get erased when you close your browser, others (permanent cookies) exist on your hard drive until you remove them.

Why is it important to clear cache and cookies?

While the cookies are definitely good for the website's marketing team, they might turn out to be useless for you. Some sites raise prices with every new visit by the same user; some offer you the items you might not want to see again (like items you already purchased) or show you old usernames you don’t use anymore. 

If you feel like your browsing experience isn't as pleasant as it was before, maybe the outdated cookies are to blame. So, here's how to clear cookies on your Mac. 

How to clear cookies: the quick way
