## Description

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
<ul><li>Auto-groups every non-pinned tab into a tab group named after its container.</li><li>Reuses the container's color, mapped to the closest tab-group palette color.</li><li>Auto-collapses inactive container groups when you switch tabs, so only the "profile" you're using stays expanded. Toggle in the options page.</li><li>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.</li><li>Persistent container ↔ group mapping, so a background script restart doesn't fragment groups.</li></ul>
Requirements
<ul><li>Firefox 139+ (when the WebExtensions tabGroups and tabs.group() APIs shipped).</li><li>Multi-Account Containers feature enabled.</li></ul>
