Yeah I think we are all talking at odds - I've used Chrome for years but always signed on with Sync as I have Chromebooks and Android devices also using Chrome and share bookmarks and extensions across all versions. 81 and i'm not liking the new interface, looks like firefox now. i don't sign into the browser user icon, is that what everyone refers to when signing out?
not sure how people clear their history but if you do it and you have to sign out of something then it's wasn't cleared correctly or you have auto sign-in enabled. i clear the history and if i go to gmail i need to sign in again. I don't know why so many say to log out of gmail when i never do.
