About This Extension
The Firefox Multi-Account Containers extension lets you carve out a separate box for each of your online lives – no more opening a different browser just to check your work email!
Under the hood, it separates website storage into tab-specific Containers. Cookies downloaded by one Container are not available to other Containers. You can even integrate individual Containers with Mozilla VPN to protect your browsing and location. With the Firefox Multi-Account Containers extension, you can...
- Sign in to two different accounts on the same site (for example, you could sign in to work email and home email in two different Container tabs.
- Keep different kinds of browsing far away from each other (for example, you might use one Container tab for managing your Checking Account and a different Container tab for searching for new songs by your favorite band)
- Avoid leaving social-network footprints all over the web (for example, you could use a Container tab for signing in to a social network, and use a different tab for visiting online news sites, keeping your social identity separate from tracking scripts on news sites)
- Protect your browsing activity in individual Containers using Mozilla VPN, so you can shop while travelling abroad but check your bank account from a server in your home country.

User reviews
Using this plugin is much better and easier than creating profiles in Firefox manually, because instead of having to open a new window for each profile, with this plugin you can view different profiles in a single window.
This greatly minimizes memory usage (up to 5 times less).
Browsing between profiles is much more intuitive and organized, as you can distinguish each profile by the color of the tab and identify the name of the profile that is displayed in the navigation bar.
This plugin is without a doubt the best profile manager currently available in all browsers I have used.

I've been using containers since they first came out. I totally love this. I can isolate my banking and financial activity on a Banking container tab, and keep my work activity kept inside a Work container tab. Nice.
The only thing I'd been wishing for was that I could have a default tab assigned for when I open up Firefox.
The beauty of this add-on, is that I can assign containers to specific websites, and every time it comes up, I no longer have to click on a URL then either move the URL to a container tab already opened (default is no container), or open FF and open a container tab, then paste in the URL.
Now, when I go to a bookmark, it's one & done. You even will get a message for one you've recently assigned a tab, asking you if you want that to be the default tab for it. Perfect. Highly recommend this as well.
