It's not exactly the same though... I have clients where we access a Google account, which has access to Google services... it's like synching a whole Google eco system. Everything is staked on the Chrome login - Gmail, Analytics, Tag manager, password synch...

It could be undone, but those frackers at Google make it so easy. And so much is built off of Gmail as the mail service.

Also, there's `firefox -P <profile>`.
