Workspace Manager by dvestezar

Workspace Manager keeps browser windows, native tab groups and tabs organized into persistent workspaces.

Save, restore and switch between multi-window workspaces, preserve native tab groups, and recover the last used session directly from the toolbar popup.

Tab lifecycle management helps reduce resource usage:

• AUTO — discard inactive tabs after a configurable delay.
• KEEP — protect important tabs from automatic discard.
• DEEP — keep selected tabs discarded until they are used again.
• Exact URL and hostname lifecycle rules.
• Search and combined filters for large tab sets.
• Workspace import/export and optional Firefox Sync for lightweight settings.

Workspace snapshots, lifecycle state, statistics and debug history stay local. The extension declares no data collection.
