GitSyncMarks di Joe Mild

GitSyncMarks syncs your Firefox bookmarks with a GitHub repository — bidirectionally, automatically, and without any external server.

Features:
• Per-file storage: each bookmark is an individual JSON file — human-readable and diff-friendly
• Three-way merge: automatic conflict-free sync when changes happen on both sides
• Full Firefox support including the Bookmarks Menu folder
• Sync profiles: real-time, frequent, normal, or power-save
• Auto-sync on every bookmark change (debounce configurable per profile)
• Periodic sync to detect remote changes (1–120 minutes, configurable)
• Manual Push, Pull, and full Sync via the popup
• Conflict detection when automatic merge is not possible
• A README.md with all bookmarks is generated in the repo for easy browsing
• Automation: add bookmarks via Git, CLI, or GitHub Actions — no browser needed
• Import/Export: back up and restore bookmarks or settings as JSON files (clear UI with file picker)
• Theme: light, dark, or auto (system) for options and popup
• Multilanguage: English and German with manual language selection
• No external server — communicates directly with the GitHub API using your Personal Access Token

How it works:
1. Create a GitHub repository for your bookmarks
2. Generate a Personal Access Token with the "repo" scope
3. Configure GitSyncMarks with your token and repository
4. Click "Sync Now" — done!

Each bookmark is stored as an individual JSON file in your repository, organized into folders that mirror your Firefox bookmark hierarchy (Bookmarks Toolbar, Bookmarks Menu, Other Bookmarks, Mobile Bookmarks). A README.md gives you a clean overview directly on GitHub.

Automation:
You can add bookmarks without even opening Firefox. GitSyncMarks includes a GitHub Actions workflow (add-bookmark.yml) that lets you add bookmarks via the GitHub web UI or the command line:

gh workflow run add-bookmark.yml -f url="https://example.com" -f title="Example" -f folder="toolbar"

You can also create bookmark files directly in the repository — just add a JSON file with "title" and "url" to any bookmark folder. The extension detects new files automatically on the next sync.
