Amazing and helpful. Makes working with multiple Microsoft accounts for different things so much easier. Also works with Facebook Container extension. Makes everything a bit more private with how it contains cookies.

Productivity savior. Makes my life so much easier as a consultant with multiple client profiles.

this extension is perfect!! i used to use multiple browsers with dif accounts on each, but now i can use just one browser and easily jump around between my numerous accounts. works as advertised.

Just like Moz://FifthAxiom : this module is great "on paper" but it lacks a lot of options and default behaviours to be useful in an everyday situation.

You should be able to easily manage the list of sites (or wildcards) assigned to a container, this basic setting should avoid new tabs (if the domain name does not match) to be opened in the same container thus breaking the tracking.

Please improve this great promising tools.

Works very well! The following things would make it perfect

- a button to split the tabs for each container in windows, so a firefox window for each container
- why are the colored bars not full width? Small thing but a bit annoying to look at.

Thank you Mozilla!

An essential add-on. It alleviates the pain of handling multiple sessions and helps organise the tabs. Also, the color highlights look pretty.

There is scope for improvement by introducing Container Windows which may designate an entire window to the same profile, thereby reducing tabs juggling and remove the need to remember to open certain link in certain container.

Works very well, till now!

Einfach toll, wie man simpel verschiedene Umgebungen im Browser haben kann und keine von denen den eigenen Browserverlauf auswerten kann. Super gemacht, Mozilla!

Excellent extension for many points of view (separation, security, privacy etc.)

Please improve it with following features:
1. Open links from bookmarks or bookmarks toolbar (right-click) in containers
2. Sort containers
3. Edit links within content o container (modify next to existing add and delete)
4. Permits wildcards or regexp for links within container
5. More icons to select


Keep up good works

This is extremely useful both to protect my privacy and keep environments separate. There are two essential features missing, in my opinion, though.
First, the option to reorder the categories. As it is now, if I want my tabs to appear in a different order when I click on "Sort tabs", I have to manually delete the containers and recreate them.
Second, for users who keep lots of tabs open (like me), it would be nice to have sessions only within one container, so that everything in the session will be automatically opened within it. At the same time, other tabs opened in different containers would stay stored so that, next time you open a default session, all types of tabs will be opened together.

Nice and useful feature. It solves so much privacy concern.
Would be nice to associate the current tab directly to a container, without having to use the '+' or open in new container and copy/paste the address.
Also, having the option to add icons from local files or, if this is not possible, from emoticon tables.

Nice and useful feature
Would be nice to assosciate the current tab directly to a container, without having to use the '+' or open in new container.
Also, having the option to add the icon selected would be helpful as well, otherwise why is the option to choose an icon available in the first place?

I use this in conjuction with Amazon Web Services to log into multiple accounts at the same time. It works very well. I do not like that it shares the same CTRL+. shortcut button that 1Password X does, though 😢
