This is an absolutely brilliant extension, the setup is super simple, you can create as many custom containers as you like. Personally I've kept all facebook owned sites in the facebook container, I've then got one for all google owned sites, one for twitter and then general ones for the different types of sites I visit, so tech, news, general, personal, banking. Basically you create the containers, create a new tab in the container, go to a site and then tell the extension to always open that site in that container. Bingo, you're done. And, the longer you have it, the more sites you find yourself adding to each container. This coupled with Privacy Badger and HTTPS everywhere and I know less of my information is leaking out. I will say, it's sad that the online world has now got to a point with tracking that we have to do this sort of shit. But, if it forces the likes of Google, Facebook et. al. to change their ways then I'm happy to do it.
