Version 1.6.2
Released Apr 30, 2026 - 82.46 KBWorks with firefox 140.0 and later, android 142.0 and laterVersion 1.6.2 — Release Notes
This release rebuilds the sync architecture to eliminate workspace conflicts when using Firefox Sync across multiple devices.
Conflict-free multi-device sync
- Each device now maintains its own independent workspace snapshots.
- Devices no longer overwrite each other's data through Firefox Sync.
New in Backup & Restore
- Give your device a recognisable name in the new "This Device" section
- "Other Devices" shows workspaces synced from your other Firefox Sync devices
- Pull selected workspaces from another device using the existing review panel
Migration from v1.5.3
- Existing workspaces are automatically migrated on first launch — no action required and no data loss expected.
- Note: tab group names from v1.5.3 could not be recovered (they were not correctly saved in the previous version).Source code released under MIT License
Older versions
Version 1.5.3
Released Apr 30, 2026 - 42.07 KBWorks with firefox 140.0 and later, android 142.0 and later- Backup & Restore — a new dedicated page (opened via the toolbar icon menu) lets you export all your workspaces to a JSON file and restore them on any device.
- Selective restore — when importing a backup, you can review the contents first and choose exactly which tabs to restore, workspace by workspace. Tabs are added individually with no forced overwrite of your existing workspaces.
- Tab group support in restore — tabs that belonged to a named group in the backup are restored into the correct group (or a new group is created if none exists).
- Live restore for open workspaces — if a workspace window is already open when you restore, selected tabs are added directly as live tabs in the correct container. For hibernated workspaces, tabs are added to the snapshot and will appear the next time you open that workspace.

- Internal code documentation improvements: all comments translated to English and security-context explanations added to clarify how container assignment, data compression, and Firefox Sync work.
