Great extension! Really handy to have different "views" into a website, each with a different account and cookies, etc.

I had trouble disassociating sites from Always opening in a particular container, but here's how you do it: You have to open the extension from the toolbar > Manage Containers > My Container XYZ > Manage site list.

The interface is odd because a similar but different set of options appear when you hold down the new tab button and choose Manage Containers, it doesn't have the Manage site list option there! The Manage site list isn't in the Extension settings either.

I had originally accidentally associated google.com with a container, so whenever I did a search, it asked me if I want to open the website in the container or no container.

Really great extension. I love being able to work with multiple google accounts in a single browser without having to re-log in. Highly recommended.

Love it. Would enjoy more basic customization, like more colors for container tabs, maybe more icons.

This extension is absolutely brilliant when working with multiple cloud services accounts and keeping a good work/personal separation

Great addon. Use it everyday for my daily tasks. It gives ability to switch between profiles on the same site

A nice intuitive approach to data separation, which simplifies my work-from-home process greatly by allowing me to separate all my work logins from all my personal logins, and even run them side-by-side in separate tabs. It can also be augmented by other addons (Temporary Containers) to open multiple separate sessions on a site at once.

Many workflows that other people would pull out a whole new browser for just require opening a tab in a different container.

This is one of those "bread and butter" addons that does something super basic but you wonder why it isn't the norm in every browser.

Amazing useful, I installed in every Firefox installation I work with

I have a container for google search so I can search without a sign-in while remaining signed in to other google services. Use "Limit to designated sites" to stop links opening in that same container. Works perfectly.
