## Description

Silo is the automation layer on top of Firefox Containers. Firefox Multi-Account Containers gives you the building blocks; Silo adds rule-driven behavior so sites reliably open in the right container without constant manual tab management. It supports the enforcement of always (or never) opening sites in a given container and has keyboard-shortcut-friendly workflows for faster control.
