Workflow01 by ntrezowan

Workflow01 is a single-window workspace manager for Firefox. Instead of juggling dozens of tabs across multiple windows, organize them into named workspaces and switch between them instantly.

How it works

• Click the toolbar icon or press Ctrl+Shift+Y (Cmd+Shift+Y on Mac) to open the popup
• Type a workspace name and press Enter to create one
• Your tabs are saved automatically as you browse — no manual saving needed
• Switch workspaces with one click. Your current tabs are saved, then replaced with the target workspace's tabs
• Create a new workspace from your active tab to split work off into a separate context

Features

• Single-window tab replacement — no extra windows cluttering your taskbar
• Continuous automatic tab tracking — saves on every tab open, close, and navigation
• Active workspace highlighted — in the popup with tab count per workspace
• Confirm dialogs — before deleting or switching workspaces
• Export and import — workspaces as JSON for backup or sharing
• Light and dark theme — follows your system preference
• Keyboard shortcut — Ctrl+Shift+Y / Cmd+Shift+Y on Mac

Permissions explained

• tabs — needed to read and manage tab URLs for saving and restoring workspaces
• storage — needed to persist your workspace data locally on your device

No data is collected or sent anywhere. Everything stays on your machine.
