Sandboxie Support

Let's say I get a keylogger in the sandbox. If I'm correct, it would track me on my non sandboxed windows too, right? But if you delete the sandbox, which would remove the keylogger, would it then be gone? If not, would it be if you reboot? (Sorry if this question is silly I lack technical knowledge...

If Firefox is your browser, when you allow bookmarks to be saved out of the sandbox, history gets saved as well. You can work around that by setting Firefox to Never remember history or Use custom settings for history. For the latter, untick Remember my browsing and download history. Firefox Tools>...

I'm using the latest beta because the other version stopped working.
When I go to a website in the sandboxed browser, it remembers it on my normal browser.
Does this mean my session wasn't sandboxed at all? how do I fix it?

For some reason, it is remembering my browsing history. Does that mean my session was not sandboxed? :/
