Extension Metadata

About this extension
Firefox containers let you separate browsing sessions. The problem? External links from Slack, Discord, email, or any app, as well as new tabs and right-click link openings ignore your containers.

Containacious fixes this. Every new tab and external link opens in your chosen container for that window. It makes Firefox containers behave like Google Chrome Profiles.

The source code is available on GitHub.
