For most Google SPAs I use an appify tool, that contains the site in a single app webview with no shared cookie store. Then in my main FF browser I have cookie crushing on, so that when I navigate away from a domain, all cookies that were created are destroyed. Ok, I spend my life filling in captchas, but to me that’s a signal that it is working and Google aren’t overly sure who I am.
