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.

A extensão é ótima, funciona muito bem, outros navegadores concorrentes não tem uma extensão como essa gratuita. Os diferentes contêineres são facilmente identificados, evitando confusões.

I'm completely satisfied with this extension. It allows to keep multiple sessions (i.e. session cookies) to the same website thus allowing multiple logins. As a developer I use this for verifying the functionality of webapps that have multiple roles. Thus extension fully replaces SessionBox that was available on Chrome and now no longer works. Thank you.
