Windowed Container Workspaces EN

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

Privacy & Data
Windowed Container Workspaces stores and processes the following data:

Stored locally on your device (storage.local):
- A randomly generated device ID
- Your device name (auto-generated or manually set by you)
- Mapping of open workspace windows

Stored locally and optionally synced via Firefox Sync (storage.sync):
- Workspace names, colors, and icons
- Tab group names, colors, and collapsed state
- Tab URLs and page titles
- Tab pinned state
- Device ID and device name

This data is stored by Firefox as extension data.

If Firefox Sync for add-ons is enabled by the user, Firefox may synchronize this extension data between the user’s own Firefox profiles/devices using Mozilla Firefox Sync.

Firefox Sync feature is delivered by Mozilla Firefox, not by the Windowed Container Workspaces extension.

The developer does not receive, access, store, process, sell, or share this data.

The extension does not use analytics, telemetry, advertising, tracking scripts, or any developer-operated backend server.

The cookies permission is used only for Firefox container-related functionality. The extension does not read, store, export, or transmit cookie values.

The Export/Import backup feature saves data only to your local filesystem.
No network requests are made.

Sync requires a Firefox account with Sync enabled.
