Excellent user experience; excellent functionality.

Works better than I expected. I use it often for logging into a website using multiple accounts.

It would be useful to have an option to prevent other sites (than those which were assigned to the container) from opening in the container. Like the 'Facebook Container' extension does. If I click a link on facebook.com that directs to other site than facebook, it opens in default container.

Outstanding extension. Tools like this really put a lot of power in the hands of the user for protecting their privacy. It would be perfect if you could use it in private windows and reorder the container list too.

It'll be even greater if I can drag and reorder my containers

Really helpful especially for social media sites like Facebook or Discord

This is hands down one of the best browser features I've used! It helped me fully convert to using Firefox both for work and personal stuff.

Amazing I love this container. this is the reason I use firefox and not chrome.

It's OK and is enough to make me feel I can switch from Chrome's easy multi-profile support. But the containers add-on does not appear to sync settings via Firefox account, so that is a big pain. It also does not appear to let you select a default container for new tabs, which is frustrating. That later wish is actually the only setting I can imagine wanting to be able to set differently at home & work, so some care to be taken there. Keep working on it!

I find the implementation of Firefox containers extremely frustrating to use.

The Firefox containers require that I keep my current context in my mind when taking any action.

If I am on a container tab for for and I press "cmd-t" to get a new tab, I do not get another work container tab. Instead I get a non-container tab (or default container). Several times a day do I realize that I've been doing a specific kind of searching (google research) or general browsing in the wrong container.

This pollutes my container identity, history, and website preferences. My work search history is now full of non-work stuff. My search results are less relevant. My "goof around" container is now full of work results, and vise versa.

I prefer the Chrome model, where one whole window, and all it's tabs, are one "profile". This makes it much easier to use and think about.

This is an awesome, game-change extention! It's so great to make each website to have each own information! I'd like only to suggest the sync of the configuration between devices as it's a problem to have to configure which website to open with each container by default in each machine
