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!
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.
