I want to allow cookies for a domain but only over HTTPS -- not cookies from the same domain that come from HTTP. For example, I don't want any http://www.google.com cookies, but I do want to allow https://www.google.com cookies (because Calendars are there).

Is there a way to do this? Does the goal even make sense?

In Chrome, it only allows domain names, not URLs, to be added to the cookie exception list. In Firefox, it allows a protocol, but it only records the domain name, and if you click "Allow" or "Deny", it changes the same entry in the list.

    Maybe it matters for you; if so then you might need to limit your question even more: cookies that are served through HTTPS, but do not have the secure flag set, will also be sent back to the web server when using plain HTTP.

NoScript for firefox solves this problem:

  • And NoScript is a very good one, have a look to their changelogs if you want to learn that you know nothing to javascript security ^^

Is there a way to do this?

Privoxy can do this for you and works for the browsers you change the proxy of.

As it doesn't handle HTTPS traffic it will only filter HTTP traffic, you could use cookie crunching

The user.action file should look similar to this:

{ +crunch-incoming-cookies +crunch-outgoing-cookies }
/ # Match all URLs

Does the goal even make sense?

Although it will make you more secure, I don't see the need to do it.

You might as well break some sites you use on a daily basis, but Privoxy allows you to allow those sites...
