Great to see this feature being added to other browsers. I use the Firefox Multi-Account Containers, Temporary Containers, and Containerize extensions to manage my browsing and it's (mostly) a very nice experience. There are some rough edges for certain tasks, but I've not had any desire to go back to containerless browsing for a few years now.

For me, they are completely essential and we're the killer feature that kept me on Firefox. That, and I never liked Chrome anyway.

> the killer feature that kept me on Firefox

precisely, I do occasionally have to switch browsers which is incredibly frustrating but that's more of an indictment of the current state of the web than FF in my mind

Same. I often describe it as a killer feature when people ask me "why firefox?" It surprises me that so many people don't even know they are a thing!

How do you use them differently than you would have used profiles?

I can:

- Right-click and re-open a tab in a different container

- Automatically switch to a container for certain domains

- Organise tabs of different containers amongst each other (eg. same site opened in different containers next to each other)

- Not clutter my window manager just to separate browsing data

Because profiles are a different thing and are a state of your browser.

Container tabs are the state of your browsing session.

Yes, a different browser provides you with a different session, but its overkill.

Scenario: I deal with multiple AWS accounts, which require me to log in to each one with SSO. Container tabs allow me to access each one as different colour coded tabs at the same time without being kicked out when it overwrites my session.

Second scenario: I have multiple clients, I would use different profiles to separate out plugins for password management requirements, different bookmarks, etc.

There are a disappointing number of sites that are stateful, like Service Now and container tabs make them bearable.

I have 3 different bookmarks that open 3 different Gmail accounts. I use an AWS SSO plugin to open each account in its own container. My wife and I have several other services where we each have an account, so on our media pc at the TV we can both be logged in at the same time in different tabs. I always open sensitive stuff like banking in its own container. I keep various online stores (where I will be paying for stuff with my credit card) separate from casual browsing. Tabs are colour coded too.

I am extremely happy that I can now have containers with all 3 browser engines. Brave to represent Chromium, Firefox had them for a long time, and the WebKit-based Orion recently got them as well.
