Sounds very much like my experience except for the crash (which I didn't have) and the prior good experience - since I just purchased it for the first time.  I'm not sure that Cookie ever removed anything from Safari??  I uninstalled it and have given up on a refund - the hoops between Apple Store and Sweet Productions are not worth it for $15 - a write off charged to experience.

We seem to be going around in circles here. I open and close Safari at least once a day. These cache cookies have been there for days - no matter what I do except I can get rid of them one at time in Safari preferences. Now, they don't show up in Cookies at all.

I just quit and restarted Safari and immediately went to Show Cookie. It says I have 58 favorites and 108 cookies?? Some of the Favorites changed and I have old needed websites with wanted data and some new ones marked as Favorites!

Tell me why I shouldn't get a refund on this software.

Here's a shot from the Application Scripts of my Library:

This was intended to show you that the scripts are installed.  To be more confident, I reinstalled them.  To be clear, Cookie is NOT doing much for me.  I repeatedly click on the manual "Remove all but favorites' and very little disappears - none of the cache cookies.

Here's a shot from the Application Scripts of my Library:

I have been running Cookies 5 for a week or so after buying from the App Store.  Just before buying Cookie and installing it, I had manually removed all unwanted cookies in the Safari preference.  I is now filled again!  All the unwanted cookies seem to be Cache.  Should those not be removed by Cookie 5?
