It's perfect at what it does.

Great! This is the most useful extension for me! Now i can login to multiple accounts of a website!

This is truly empowering for those of us that need to juggle multiple accounts. I work for an MSP and have several clients with the same providers. This extension allows me to open those different accounts along side each other.

One thing I would love to have is integration with Firefox Sync. I setup 8 different containers so far. Then I went to my laptop and found I have to set them up again. Firefox Sync would be delightful.

A good start to a truly usable multi-profile browser. One addition that would be nice would be the ability to sort the container list rather than have them simply appear in the order in which they were created.

Indispensible if you need to juggle multiple identities around!

For example, I have a personal Google identity and couple of work identities viw G-Suite. With this extension is easy to keep all those identities apart in a separate containers and never worry about messing up personal accounts with work accounts, etc.

A very nice feature (that unfortunately I found to be poorly discoverable) is the ability to set a default container for a domain/website – all new tabs opened in the given domain will automatically be opened in that container.

I do miss an option to set a default container for an entire window, so that all new tabs opened in that window would automatically be opened in that default container.

As this extension stands, it doesn't offer enough options to be truly powerful. You can't make websites truly exclusive to their containers (at least I haven't found that option) and you can't have containers that wipe out their data after you stop using them (essentially mini private tabs) and the developers don't seem to be interested in such features.

It's OK but nothing special. Too simplistic to be really useful in actuality.

It requires a bit of setting up if you're slightly paranoid; but after that, it becomes a fantastically useful extension.

One feature I didn't know I wanted but holy hell do I use it often. Ever see a youtube video you want to watch ONCE but don't want to get 3 weeks of recommendations based on it? Just use a container.

крутое расширение. Узнал о нем, когда открыл новую вкладку, увидел рекомендацию снизу. Очень круто :)

Love this. I use it all the time. I wish I could reorder my list of containers and change the keyboard shortcuts, though.

Great extension but need more visual clues that tell you in which container the current tab is. That small colored line is not enough for me.

I LOVE THEM, BUT they make Firefox crash when closing.

I love it.

I Love This Add-ons

Really useful. No need for other browsers to test or use another accounts on different websites or social networks. Great to check how a page will behave being logged-out. Very good to keep things in an orderly fashion.

Nicely done. Like others, I'd like to see synchronization. Also, container schemes, where one can edit and share setups (this site to this container).
