## Description

ContainerGate gives you control over where externally-opened links land.

When an app outside Firefox (email client, Slack, a terminal) opens a URL, ContainerGate steps in and asks which Firefox container to open it in — keeping work, personal, and throwaway browsing properly isolated.

<strong>Features</strong>
- Detects links opened from outside the browser
- Visual modal to pick from your available containers
- Per-domain rules: remembers your choice automatically
- Whitelist: trusted domains open directly, no prompt
- "Open without container" option when you need it
- Toolbar panel to manage your rules and whitelist

<strong>Requirements</strong>
Requires the Firefox Multi-Account Containers extension to provide the containers.

<strong>Privacy</strong>
ContainerGate collects no data. All rules and whitelist entries are stored locally on your device.
