Containers as Tab Groups nga HummusIm

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.
