One of the best way to protect your privacy

Great product! Easy to manage different accout on the same web site without closing any.

Very useful add-on for limiting social media sites' ability to track your online activity.

Easy to understand the usage. Great Add-On.

Works well for me as an end user. I believe this really does keep browsing activity contained. For starters, so far I saw no ads relating to my recent surfing history!

A must-have / indispensable!

Multiple accounts in one browser. Finally no need to run a separate browser for my work account!

Very useful.

It's very easy to keep my tabs separated by activity, and I love the feature of being able to login with different accounts in different containers! This is exactly what I needed.

I tested this useful addon on Waterfox , but when i click on the icon i don't see the dropdown menu.
(i read somewhere it's by design but by design of what???)
Edit:
With the help of:

I can see the menu...
Need time to test now!

Excellent Add-on,

I used this extension a few days ago and it has been a great benefit for me to protect my information from facebook and it's related services. Which helps me now to securely use the internet without giving them unauthorized access to my interests and other private data. Huge thanks to you guys at Mozilla for making this happen.

Really gives me the warm and fuzzies! Seems to be having an effect, too.

A must for every firefox browser

Normally I don't log-in to post comments or reviews since I fear tracking cookies and it's too inconvenient to open a private browsing window just to post my opinion. This add-on has changed everything.

It's been a real pain managing multiple accounts using a combination of private browsing and different browsers. There are very few features in any application that increase both convenience and security/privacy. This add-on is one of those features. Things like this are the reason I still prefer Firefox over other browsers.

I'm giving this add-on five stars even though I think Multi-Account containers is a rather dry name. Wouldn't Personas have sounded cooler?

This should be included in the browser, but I understand if they want to keep it an addon. This is perfect for developers who want to test with multiple simultaneous logons. It's perfect for anyone trying to keep their various online lives separate (e.g. work vs personal). And it's perfect for trying to get out of filter bubbles.
