Easy to manage, I loved it.

Most helpful add-on the world has ever known. Not only can you run multiple Azure sessions in parallel, for eg, but you can also just pop open a new container if you run out of free reads on paywalled freemium sites lol.

Very useful and very customizable.

Log on to the same site with different accounts effortlessly.

I have multiple Microsoft 365 accounts and now they can run in adjacent tabs without interfering with each other.

Great Addon.

I love this extension. "Open this site in your assigned container" create s some problems, but as the Developer response below explains, there is a solution.
"Remember my decision for this site" is useless in some cases. For example, I want to open multiple AWS accounts in different containers. The pages of different accounts have the same url, so "Remember my decision for this site" does not do any good.
However, the second tip - delete the sites assignments to containers works. It just opens a new page in the same container as the original page I'm coming from.
Thank you for the advise and standing behind your extension.

Works great for me and you can sync your settings with your FireFox account
