What a dumb interface. You need to make it LOUD & CLEAR what each button does. I just erased all the cookies for all of my website logins ever because the stupid drop-down menu of the "Clean" button decided to wipe out everything and not just the cookies for the site I was on. Stupid. Nowhere in any app/ext/software is something that detrimental so easy to do with the click-of-a-button, for good reason. There was no warning at all. Clearing the cookies for the current site should stand alone as it's the most common function for the average user, period. Not an opinion.
