Good job, Mozilla.

With all the options to Ask Before Deleting, you left off the one that would actually make a difference in my life.

Good Job.

Now, all I have is Mozilla cookies.

Yummy.

How and where did you delete cookies?

I accidentally clicked "remove all cookies" when I was editing cookies. My heart sank as I realized I clicked the wrong button. I was sure that something that important would have a verification step before actually removing all your cookies. I was wrong.

You can remove some or all buttons in the Cookie Manager and use the Delete key instead to remove selected cookies.

Add code to the userChrome.css file below the default @namespace line.
