Ah right. I think that's my problem too and other people are posting about it here on the forums. Cookie doesn't clear any of my Safari cookies on quit, I sync my Safari data across my Apple devices.

So does that mean we can call Cookie useless for people that use Safari?

I'm having this issue too. It appears Cookie's automatic removal is totally inoperable. I have installed the scripts.

Automatic removal doesn't work on a timer, nor on browser quit. It doesn't remove a single cookie.

BTW... you have an error in the location path of the scripts in your post.

MacOS 10.12.1
Safari 10.0.1
Cookie MAS 5.2.1
