That question came up to me, when recently working on one project I needed to restart my PC several times. And therefore, while I used 3-5 web apps I needed to log back in to each one of them again, after each restart. And I started wondering if privacy-wise that auto-clear feature is worth it or not? Has anyone maybe tested that?
I’ve been using cookie autodelete to clean crap from most sites, but whitelisting the ones I don’t want to log back in every time

another advantage is that cookies are cleaned seconds after the last tab on that website is closed
