## Description

<strong>Workspaces</strong> is a Firefox extension for managing tabs by context. Create multiple workspaces, keep each set of tabs separate, and switch in one click without losing your place. Automatic backups help keep your workspaces and tabs safe, with easy restore and JSON export for transferring them between devices.

<strong>Workspace organization</strong>
Create, rename, delete, and reorder workspaces in the sidebar. Pick emoji or custom icons, use drag‑and‑drop ordering, and manage everything inline.

<strong>Move tabs and stay focused</strong>
Move a single tab or multiple highlighted tabs to any workspace via the tab context menu. Use “All Tabs” mode when you want to reveal everything across workspaces.

<strong>Automatic backups and restore</strong>
Schedule automatic backups of your workspaces and tabs, or create them manually at any time. Choose how many backups to keep, restore previous sessions with a click, and export or import JSON files to move your workspaces between devices or keep an extra backup.

<strong>Bulk actions and utilities</strong>
Move all tabs from one workspace to another, close only the tabs of a workspace, or copy all workspace URLs to the clipboard.

<strong>History and undo</strong>
Every create, rename, move, and delete action is logged. Undo or redo from the history panel when you need to roll back.

<strong>Backup and restore</strong>
Export all workspaces and tabs to JSON, then import with merge or replace options, or restore only workspaces without tabs.

<strong>Keyboard shortcuts and theme</strong>
Toggle the sidebar and switch to workspaces 1–9 with shortcuts. ** Light<strong>  and ** dark</strong>  themes are supported.
