A nice intuitive approach to data separation, which simplifies my work-from-home process greatly by allowing me to separate all my work logins from all my personal logins, and even run them side-by-side in separate tabs. It can also be augmented by other addons (Temporary Containers) to open multiple separate sessions on a site at once.

Many workflows that other people would pull out a whole new browser for just require opening a tab in a different container.

This is one of those "bread and butter" addons that does something super basic but you wonder why it isn't the norm in every browser.

Amazing useful, I installed in every Firefox installation I work with

I have a container for google search so I can search without a sign-in while remaining signed in to other google services. Use "Limit to designated sites" to stop links opening in that same container. Works perfectly.

This is an excellent extension. I don't know why it has been hidden from search within the Mozilla Add-ons site. The only way to find it is to use a search engine.

This is one of the BEST and USEFULL Firefox add-on! I LOVE it :-) Thanks to all Devs from Mozilla Teams 👍
