My missing useful feature. Super useful.

It's a little clunky, i wish it were easier to manage a larger number of containers, and it was easier to set rules for when something should open in a container. Overall though big thumbs up to the mozilla team, this is a great and usable privacy tool

This extension is fantastic for keeping different parts of your online life organized. Each container has its own color-coded tab and separates cookies, so you can stay logged into multiple accounts at once without conflicts. It also works well with privacy tools like VPNs for extra protection. Easy to use, keeps browsing tidy, and gives you much more control over your online activity.

Essential to maintain multiple online identities, each with their own cookies/sessions.

Amazing extension, The amount of time it has saved being able to have different accounts open at the same time.

just what i needed

Really nice to have isolation per container, and I've found great utility for it, especially when I was fed up with using Google account switcher for switching between different google accounts of mine.

I love it. Thanks guys

Works well. Once you've got it set up it's unobtrusive and effective ; it's easy to set up

Very cool, this should be built in to Firefox (IMHO) but I can imagine some of the cookie following community might freak out if everyone could put this to use for their own needs. Bravo and Brava!

Bella l'idea ma assolutamente impossibile da usare perchè in pratica danneggia il corretto funzionamento di quasi tutte le altre estensioni e dei siti che richiedo l'accesso attivo!

One of the coolest things ever and I never would have thought of it. I'm no programmer but after needing to re-login to everything once I assigned containers, my observation is each container is essentially a separate instance of the browser, each container with its own set of cookies. This is a genius way to split up cookies based on how sensitive the info is, and it somehow manages to run as if I didn't install an addon that does multi-process instances in one window. I've been using Firefox ever since I started to understand cybersecurity from wiki dives and debit card fraud in high school and would just like to say this is probably the most customizable, resource-efficient/multithreaded/fast and private browser there is. That's why I have my beta studies turned on now; I want to contribute. Thank you and keep up the great work over there!
