What is Firefox Multi-account Containers?
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! Here is a quick video showing you how it works.
Under the hood, it separates website storage into tab-specific Containers. Cookies downloaded by one Container are not available to other Containers. 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)
After installing the Firefox Multi-Account Containers extension, click the Containers icon to edit your Containers. Change their colors, names, and icons. Long-click the new tab button to open a new Container tab.
Privacy in Firefox Multi-Account Containers
The Firefox Multi-Account Containers extension does not send any information to Mozilla.
Haven't I seen this in Firefox before?
Firefox Multi-Account Containers was first introduced as "Containers" available only in Firefox Nightly. It went on to be a Test Pilot Experiment, where we improved the user experience and added new features. Now it exists here as an extension that can be installed by all Firefox users.
Although you can still use the feature built into Firefox Nightly, we recommend using this extension as it has a richer user experience.








Comments and Reviews
Works great! Lets you keep parts of your online life separated into different tabs that preserve your privacy, The cookies are separated by container, allowing you to use the web with multiple identities or accounts simultaneously.
Great idea. But there is a significant bug. When you disable the add-on and re-enable it, all information about the rules is lost. And I had a couple of hundred domains crammed into a dozen containers. The thing is that I am from Russia, and here you have to especially monitor your privacy, separating pro-government sites from others. I did not make backups of these lists. I only added to them in the extension. I regret the hours I wasted on this. And I am not sure that I will not have to repeat this path if I try to use this extension again. Moreover, there is a ticket on Github about a similar problem, created in 2017, with dozens of likes and more than fifty comments. Several years to fix a critical problem is too much.
Great for users on shared PCs that don't enjoy the idea of having to constantly logging in and out of accounts. It's a real boon at work.
The only thing that'd make it even better would be a password/lock feature for certain containers. Then I'd never have to worry about my co-workers seeing all my NSFW site logins.
What about antidetect browsers like gologinapp and others? Good alternative?
It can remember which container to use for specific site.
