Hi,

It is not the add-on fault, it is the Firefox preferences that you change which still do that.
If you have changed some settings in the "Firefox" panel, within CookieKeeper preferences, it change the actual Firefox preferences.
To revert your changes, go to the Firefox preferences (call Options on Windows I think), in the "Privacy" panel, you need to set-up to what you think is good for you.

Although, if you have made, with the right click pop-up menu changes, on the permissions, to allow/ask/deny a domain cookies on some website, you may revert your changes in "about:permissions" (to do so, open a new tab, and in the address bar ("Search or enter address") type: about:permissions
There you can manage for each web site you already have visited, theses permissions.

My add-on permit to change theses functionalities. But they are not part of it, theses functionalities are built-in within Firefox.I just included them for convenience. If for some reason, you can't revert your changes, you can still reset for Firefox profile: Help menu -> Troubleshooting Information. Then "use the Reset Firefox" button.

"Not only that, but there doesn't seem to be an intuitive way to whitelist or blacklist cookie domains either."
Right click on a cookie domain, in the main cookie view -> Permissions -> Default/Allow/Block/Allow for session.

"Really clunky and poor interface, imo."
Can you explain more ? With only this sentence, I can't make things better ....
