## Description

<strong>Container Manager Pro</strong> is a redesigned dashboard for Firefox's native containers — built entirely on <code>contextualIdentities</code>, with no custom cookie handling of its own.

<strong>Features:</strong>
- Unlimited, fully custom containers — any name, color, and icon
- One-click "open current site in container," with a right-click context menu shortcut
- Auto-assignment rules (e.g. <code>github.com → Development</code>) that reopen matching sites automatically
- Favorites and recently-used containers surfaced at the top of the popup
- Workspaces — save a group of tabs across containers and restore them all at once
- Per-container statistics: open tabs, last used, unique domains visited
- Full JSON backup and restore of containers, rules, favorites, and settings
- Keyboard shortcuts for every core action
- Dark and light themes

No data ever leaves your device — everything is stored locally via <code>browser.storage.local</code>.
