Features & Capabilities

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.

Features

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

Requirements Requires the Firefox Multi-Account Containers extension to provide the containers.

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

Is ContainerGate Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

ContainerGate requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

ContainerGate is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
