I found using this, with an isolation setting for specific domains, to be a better option: https://addons.mozilla.org/en-US/firefox/addon/temporary-containers/ https://addons.mozilla.org/en-US/firefox/addon/temporary-con... An isolation policy will let you treat subdomain different from main domain. So I can use mail.google.com and still always be logged in, while a search from address bar or elsewhere will open in a temporary container that lasts only as long as the browser tab. The persistent "Google" container I have has domains mail.google.com, accounts.google.com, and myaccount.google.com.. everything else loads in temporary containers. Combine with this to remove the link stubs on SERP so you're not sending back click data if there's a shadow profile based on IP and browser metrics.. so shadow profile only knows what you searched and not necessarily what you clicked, and its cleaner for container assignment when opening links in new tabs because there's no brief hop to the same temp container google search loads in before going on to a separate temporary container for the target site: https://addons.mozilla.org/en-US/firefox/addon/google-search-link-fix/ https://addons.mozilla.org/en-US/firefox/addon/google-search...
