It's very useful extension, It's solves the use cases works well

Absolutely love this extension. It's brought a long time chrome user over to firefox.

No longer is there any need to have multiple windows open for different webmail logins.

I can stop sites from tracking me by doing web searches in different containers.

Brilliant!

I administer multiple web apps, across multiple environments. Very useful when you need to test as a user (in one or more environments), while viewing/modifying as an administrator simultaneously.

This is what I was looking for to test web apps in one browser with a different user in different tabs.

brill add on

Simply amazing. Can use multiple tabs in same window opened in multiple containers avoiding the need to open separate windows!

Awesome, everything about it is simply awesome.

About Perfect! A data privacy must have!!

It's fantastic. As an IT professional, I sign into the same portal with different accounts very frequently. This add-on saves me so much time and headache as I can use one browser for this task now instead of two or three. Highly recommend for productivity and privacy.

Useful, handful, and still worth to install because it brings better features than the native container tabs.

Awesome add-on - never knew how much I needed containers for multiple logins for single sites, until I used this! Works like a dream
