I contributed UX for a 'save cookies for this site' dropdown feature in the navbar, a poc was made which looked good, but it got lost in other work and eventually didn't land in a release that I'm aware of. Shame because that one feature would make it practical to use the recommended clear cookies behavior by default except for particular sites and overall boost everyone's privacy and security because I'm pretty sure most people turn it off after getting sick of logging in. After a couple of months I went back to Firefox and hardened it making it basically the same as LF but not being a month behind in updates. I guess I'll revisit the project now
