I'm looking for a browser extension like Cookie Time that works for Firefox Quantum. Cookie Time can remove unaccessed cookies after a specified timeframe. It will not delete recently accessed cookies. It can keep track if a cookie is recently used or not, and how long it has been since they were last used. This avoids manually fiddling around with whitelisting. I used to set it to delete cookies that haven't been accessed in around one week, but it currently doesn't work with Firefox Quantum.

I've tried Cookie AutoDelete (which is what Firefox suggested as a replacement extension) but it doesn't work the same way:
It can't detect recently used/accessed cookies. It only tracks if a cookie is from a closed tab and when that tab is closed. Its Automatic Cleaning feature won't remember cookie timestamps after browser restart even if 'Clean Cookies from Open Tabs on Startup' is disabled. It's probably designed to remove cookies within a browser session as it is supposed to be configured in seconds as supposed to Cookie Time's weeks or months.
It will delete all cookies from all closed tabs (except those manually whitelisted), and will attempt to delete after every tab close or browser restart. It doesn't touch cookies from tabs that haven't been opened yet (such as those made before extension installation). It doesn't track the time a cookie was last accessed. Cookie Time doesn't check if a cookie is from a closed tab, only cookie access times as seen in its settings configuration above (screenshot from a freshly installed Cookie Time). Cookie Time detects if a cookie is recently used or not, and how long it has been since they were last used. No tab closing or opening in the equation at all.
