Windowed Container Workspaces by brady77

Windowed Container Workspaces lets you organize your browsing into named workspaces, each running in a dedicated Firefox window with a dedicated Firefox Container.

Perfect for:
- Freelancers and consultants managing multiple clients
- Developers working across multiple projects or environments
- Anyone who needs separate logins for the same service (e.g. two Google accounts)
- People who want to keep work and personal browsing completely isolated

Features:
- One workspace = one window = one Firefox Container
- Tabs are saved automatically and restored when you reopen a workspace
- Tab groups (including names and colors) are preserved across sessions
- Workspaces sync across devices via Firefox Sync
- A badge on the toolbar icon shows which workspace is currently active
- New tabs opened inside a workspace window are automatically assigned to the correct container
- Per-workspace storage usage indicator shows how close you are to the sync limit

Sync requires a Firefox account with Sync enabled.
