Would love an option to reorder containers!!

This add on does exactly what it is supposed to do. Perfect! I can use Google services, Facebook, Twitter, and others all in separate containers.

As I manage personal, work, and educational Office365 accounts, this extension is essential to efficiently manage my online life.

A good feature which can be made better: 1) Sync opened tabs in different container across devices. 2) Send a normal tab to a container and close the original tab (currently it reopens in a new one in the designated container and so you result in having 2 tabs). 3) Make hiding a container easier (e.g. by right-clicking on the tab and have a option in that menu; currently users have to click on the add-on icon, click the tiny arrow of that container, and then click hide).

Not user-friendly despite not looking very nice. I tried selecting "alway open this site in..." "private" for addons.mozilla.org. I don't know what I am doing wrong but when I go to addons.mozilla.org it doesn't switch container. If I can't rely on this than it is useless ;(. But I love the idea (right now I am using multiple browsers)!

Edit: It shows the "Installation aborted because the add-on appears to be corrupt." error if you've changed the extensions.allowPrivateBrowsingByDefault toggle in about:config. Now it's working fine.

Ok

This extension is a life saver if you're an IT Admin that manages multiple accounts for your customers. Before I found this I wanted to kill myself managing Office 365 tenants. Now I can have dozens of tenants open at the same time without login issues.

The only reason I didn't rate this 5 stars is there is no way to easily sort the Containers list, really Alphabetical would be enough for me to rate 5 stars, but custom drag and drop ordering would be over the top. I have over a 100 containers, and often end up with duplicates as I miss them on first glance.

I think about it as of one of the best Mozilla Foundation inventions. Just brilliant (well, almost - from my POV it lucks profile list sort).

The next step I see: add add-on isolation to specific containers (so we could say goodbye to multi-profile operation finally).

This is really useful for having multiple accounts. Per-site containers could be a nice addition?
