Finally a replacement for a very old extension selectivecookiedelete that fits my needs: periodic manual cleaning of cookies with the ability to review cookies that have been saved in the browser since the last clean-up (so that I can see what should be whitelisted). I have tried Cookie AutoDelete, but it doesn't support this workflow (see issue #225 on their repo). Cookiebro solves this issue for me.

One feature that I'd like to see is a way to clear only non-whitelisted session cookies. It's a bit inconvenient that the trashbin button in the options deletes all of them, including session cookies from wl'ed domains; it goes against the idea of having a whitelist. - Disregard that, 1.1.0 is now perfect for this!

With a better title ("*bro" can put off some part of the audience) and a GitHub repo I can see this add-on going places. Thanks!
