Containers Come to Firefox Test Pilot
Containers are great. I've been using them for a bit. They definitely need a few things. Like an ability for the "new tab" to be sticky (if I'm in a container - new tab should open in the same container), and the ability to pick which container to open things in when the OS triggers the browser to open a URL. Right now it's very leaky... Say I start a registration process for a site in a container, they send a email confirmation, I click the link and it opens outside of the container, leaking the cookies. Bad for OPSEC.
