Hello, Is there a way to "sandbox" my gmail and youtube sign-ins so that I am not logged into Google across all tabs? Currently, once I have logged into gmail in one tab, firefox automatically logs me into every new tab of google search. I want to be able to check my email in one tab, and then do a google search in another tab without Google knowing who I am when I am doing my search. It's enough the Google has access to all my emails. I want minimize the disclosure of who I am to Google.

Thanks, Sam
