Hi, I'm trying to figure out how to browse the web without each website knowing that I have other sites open. For example, I don't want there to be any way for facebook to know that I'm also logged into gmail in the next tab. The only way I know to do this is to have several browsers installed, and separate services that way, FB in FF, Gmail in Chrome, etc... Also, I'm wondering how private mode works in FF, is there really no history or cookies being kept at all or are they stored and then deleted at the end of the session? I figure the later because otherwise sites that require cookies, like gmail, wouldn't work, yet they do. Opera seems to do something different. You have "private tabs" and I wonder if that really means that each private tab is truly isolated/sandboxed from the other tabs, both private and public. Hope my questions are clear. Thanks yall.
