Session Flow szerző: PaxIgnis

Your Firefox windows and tabs, organized in one tree.

Session Flow is a free, open-source Firefox extension that brings your open tabs and saved sessions together in a dedicated window. Nest related pages, group windows under notes, and set work aside without keeping every tab open.

Features

• Arrange windows and tabs into collapsible branches with drag and drop.
• Save individual tabs or entire windows, closing them in Firefox while keeping their place in your tree.
• Add notes, meaningful window & tab names, and separators.
• Take snapshots manually or automatically. Preview and restore a complete session or selected items.
• Export snapshots as JSON and import supported exports from other session managers.
• Work with Firefox containers and tab groups.
• Customize keyboard shortcuts, tree actions, and startup behavior.

Getting started

Click the Session Flow toolbar button or press F2 to open your tree. An onboarding guide introduces the main features after installation.

Privacy

Your session tree, settings, snapshots, and favicon cache are stored locally in your Firefox profile. Session Flow has no analytics or tracking and does not send your browsing data to its developer.

Website icons may be retrieved from websites and their icon hosts. Fetching missing icons and refreshing cached icons require optional website access.
