Features & Capabilities

Container Tab Groups treats every Firefox Multi-Account Container as a profile by automatically placing its tabs inside a native tab group with the container's name and color.

Features

Auto-groups every non-pinned tab into a tab group named after its container.
Reuses the container's color, mapped to the closest tab-group palette color.
Auto-collapses inactive container groups when you switch tabs, so only the "profile" you're using stays expanded. Toggle in the options page.
Reacts to live changes: tabs created, attached to another window, or moved to a different container; containers renamed, recolored, or deleted; tab groups deleted manually.
Persistent container ↔ group mapping, so a background script restart doesn't fragment groups.

Requirements

Firefox 139+ (when the WebExtensions tabGroups and tabs.group() APIs shipped).
Multi-Account Containers feature enabled.

Privacy

This extension stores no remote data, has no telemetry, and makes no network requests. Source code is open under MIT on GitHub.

Is Containers as Tab Groups 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.

Containers as Tab Groups requires a few sensitive permissions. 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.
