Nice feature

This app fixes the problem of having two O-365 accounts and MS not being able to keep them separate. Also great for reducing the number of cross-site tracking and marketing. I don't get as many ads for things I've already purchased as I used to. The only issue I have with it is that you can't pin an entire subdomain to a container. If a site uses different hostnames for different functions, you have to specifically pin each one (AWS does this a lot). If you lock the container so other sites don't accidentally open in it, you also can't open a new hostname under a domain that's already part of that container.

Can't work without this. Should come standard as part of the browser.

Works wonderful for separating my work and private accounts.

with growing threat of online fraud, I feel this is one of the easiest steps to prevent fraud.
I use one container for banks, One container for shopping sites and one for regular use.

Thanks Firefox for supporting in difficult times.
