(even) more privacy with Firefox Containers

Being wary of all things tracking by Google & Facebook, both of who’s products I love but data capturing practices I hate, for the last 4 years or so I always logged in into these in “Private browsing” sessions in Firefox (because why trust the worlds biggest advertising platform with your privacy, right?)
Now I just “discovered” that the Mozilla team have rendered that somewhat clumsy procedure -which required me to log in each time I restarted my computer or browser- redundant with their “Firefox Multi-Account Containers” add-on, allowing you to contain entire sessions to one (or more) tabs;


So now I have one browser window with a couple of tabs in the Google container, one tab in a Facebook container and all others in the “default” container where Google & Facebook can’t track me (fingerprinting aside, but there’s an option for that).
