Just moved to Firefox 57 and needed a new cookie manager. This one fits the bill in general, but there is a feature missing.

At times I am at a web site where I need to have cookies enabled, but it may not be the site I'm on (e.g. captcha). I would like a simple way to toggle on and off the ability to graylist all cookies. I believe this is the same as checking the Firefox "Accept cookies from websites" option. I got used to this in a previous addon, which is not compatible with FF57.
