lefred's GroupKeep by lefred

lefred’s GroupKeep helps you save your Firefox tab groups and restore them whenever you need them.

You can save the active tab group or all tab groups in the current window, then restore them later in the current window or in a new one. Saved groups can be renamed, searched, deleted, exported, and imported.

When Firefox Sync is available, GroupKeep uses Firefox’s built-in synchronized extension storage so your saved groups can appear on your other Firefox desktop installations connected to the same Mozilla account.

Features include:

• Save the active tab group
• Save all tab groups in the current window
• Restore groups in the current window or a new window
• Preserve group titles, colors, tab order, and collapsed state
• Search saved groups and tabs
• Rename and delete saved groups
• Export and import JSON backups
• Synchronize saved groups through Firefox Sync
• Fall back to local storage when Sync storage is unavailable

GroupKeep does not use analytics, advertising, remote code, or external servers. Saved tab-group data remains in Firefox storage and is only synchronized through Firefox Sync when enabled.
