There are way too many sites that send me cookies. I don't really want to keep them. However, many sites don't work at all without cookies. I've decided to do three things:
- Allow sites to set cookies, because many sites require cookies.
- Don't allow third-party cookies, because that's mainly used for tracking people across sites.
- Erase most cookies when I close the browser; I allow only cookies from a small set of sites to remain between browser sessions.
First, I allow cookies for the originating site only, which turns off third-party cookies. I keep cookies until I close Firefox. I also set Exceptions and set each site whose cookies I want to keep to Allow.
