Workflow01 v5.0 is a behavior and reliability update.

Creating a new workspace after the first workspace now opens a fresh blank tab and does not move the active tab out of the current workspace. Switching workspaces uses Firefox tab visibility only: tabs are shown or hidden, not closed and recreated. Workspace switching does not intentionally reload or discard tabs.

This version replaces workspace-name tab ownership with stable internal workspace IDs. Active workspace state is stored durably in browser.storage.local instead of relying on in-memory background-page state. Tab ownership is stored on tabs through browser.sessions.setTabValue() using the key workflow01.workspaceId.

The extension uses only local WebExtension APIs: tabs, tabHide, storage, and sessions. It does not transmit user data outside Firefox

v4.0
Rewrote the persistence layer to tag tabs via the sessions API instead of storing URL lists and recreating tabs on startup. This eliminates the tab-duplication bug (workspaces accumulating dozens of copied tabs across restarts) at the root — tabs are never recreated, so they can never multiply.
Tab counts are now computed from actual live tabs, so they never drift from reality
Added "Reset all workspaces" link to recover from any corrupted state
Requires the sessions permission
