There is currently a bug with the popup, where you have to click "Done" every time, which should be fixed soon (see issue 2813 on the mozilla/multi-account-containers GitHub repository).

This extension has always been helpful so I won't rank it down just for one mistake :)

An excellent choice if you want to have multiple online profile; it helps me a lot in my presentation and training.

Great extension! The only issue I’ve encountered is with syncing — it seems to have a bug. I never choose “Always remember to open this site with,” yet it keeps automatically assigning websites. Once I disabled Sync, the issue disappeared. I wish there were an option to turn off this feature entirely. Aside from that, it works perfectly!

Amazing must have tool has completely fix dealing with multiple accounts on services.

As others have noted though if the Rate this extension pop-up doesn't go away soon, the stars are going to start dropping.

Excellent!

It keeps things in order, useful .

Essential add-on!

One of my must have addons for task separation, and I feel it is mandatory for keeping tracking cookies completely contained (pun intended). Worthy of being built in to the main browser I think!

The only issues I have are caused by my choices, e.g. Paypal opens in a finance container, while shopping websites open in a shopping container, and sometimes I need to proceed to/from Paypal from the shopping website.

does what it needs to :D
