Container Manager автор Simar Randhawa

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

Features:
- 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. github.com → Development) 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
