How to clear cookies for one site in Firefox

There is a user-friendly way of seeing what websites have stored cookies in your Mozilla Firefox and removing the cookies for the site you want without accessing it. However, this method only shows the websites together with the number of cookies each of them created, without displaying further details about the cookies, like their names. To begin, press the Open Menu hamburger button in the top-right corner of your browser window, and then click or tap on Options in Windows or Preferences in macOS.

Access Options or Preferences from the drop-down menu

Next, click or tap on the Privacy & Security tab from the left sidebar and, on the right, scroll down until you find the “Cookies and Site Data” section. Then, press the Manage Data button.

Manage Cookies and Site Data

Mozilla Firefox loads a pop-up window called “Manage Cookies and Site Data,” where you can view all the websites that store cookies in your web browser. While you can see how many cookies each website stores, you cannot see those cookies. Use the Search websites field on top, if needed, to find the website whose cookies you want to remove. Then, click or tap on it and press on Remove Selected. Don’t forget to press Save Changes at the bottom of the pop-up.
