Tab Stash Folder Organizer

A Firefox extension that solves Tab Stash's date format and sorting limitations by automatically organizing Tab Stash bookmark groups chronologically.

The Problem

Tab Stash is a powerful tab management extension, but it has limitations that make organizing large collections difficult:

1. Hardcoded US Date Format (Issue #147) - Tab Stash uses MM/DD/YYYY format regardless of user locale, and Firefox's Date.toLocaleString() doesn't respect locale settings on macOS (Bug #476419)

2. No Automatic Sorting (Issue #606) - No built-in way to automatically sort stashed tab groups by date, making it hard to find recent saves

3. No Date Format Customization - Users can't choose their preferred date format (ISO 8601, DD/MM/YY, etc.)

The Solution

This extension organizes Tab Stash bookmark groups by reading the ISO 8601 timestamps that Tab Stash embeds in folder names and sorting them chronologically (newest first).

Features:

• Chronological sorting of Tab Stash groups by date
• Safe backup system with one-click revert
• Works with any bookmark folder containing ISO 8601 timestamps

Installation

From Firefox Add-ons site.

The extension recognizes ISO 8601 timestamps in folder names like:

• backup-2025-10-11T15:30:00.123Z

Folders without valid dates stay at the bottom.
