Workspaces Firefox

Workspaces

Organize tabs into dedicated workspaces, switch instantly from a clean sidebar, and keep related tabs grouped and hidden when you’re focusing on something else.

Features & Capabilities

Workspaces 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.

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

Move tabs and stay focused 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.

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

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

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

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

Is Workspaces Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Workspaces requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Workspaces may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
