Getting Rid of Bad Cookies on the Mac

I will try to refrain from making the obvious joke about there not being any such thing as a 'bad' cookie, but I had a teacher ask me the other day how to get rid of her daughters email login information on her work computer – every time she wanted to check her email, she had to delete the username that the web browser so graciously entered for her convenience.??

When a web browser offers to save your login or other information, it creates what is called a 'cookie' file. The purpose for this??is to make your next visit to the site a little easier, faster or more friendly. It's usually pretty simple to just delete all cookies on your machine for a browser, but that's a heavy handed fix for a seemingly minor issue like this.??

The steps to delete an individual cookie is a little more involved to do, but I've created a screencast that will show you the process.??

I've included the steps for both Safari and Firefox – leave a comment on this article if you'd like the process to be shown for Chrome.

Here we go!


  1. Thanks Clint! I always cleared all my cookies, was a pain having to re- enter stored info that I wanted! You solved yet another problem!

  2. Glad it helped, Chris. It was something that I never really knew how to do either, so I thought that I’d post it.
