Note: I am not a Firefox user and don't follow their latest news, but I thought it was interesting to share. I can see the advantages and disadvantages when compared to Chrome's profile management, but that's not for this topic.

"Containers is an experimental feature that lets you separate your work, shopping or personal browsing without having to clear your history, log in and out, or use multiple browsers.
Container tabs are like normal tabs except sites you visit will have access to a separate slice of the browser's storage. This means your site preferences, logged in sessions, and advertising tracking data won't carry over to the new container. Likewise, any browsing you do within the new container will not affect your logged in sessions, or tracking data of your other containers."

"Although the privacy.userContext.enabled preference described above may be present in other versions of Firefox, the feature may be incomplete, outdated, or buggy. We currently only recommend enabling the feature in Nightly, where you’ll have access to the newest and most complete version."
