Linkding Extension Plus

A feature-enhanced browser extension for the linkding bookmark manager — built on top of the original linkding-extension by Sascha Ißbrücker.

What's new

This fork adds a number of UX improvements focused on fast bookmark browsing directly from the popup:

Feature	Description
Bookmark Tree as default view	The popup opens directly with the bookmark tree instead of the add-bookmark form
File-explorer design	Folder icons, favicons per bookmark, ├/└ tree connectors, compact layout
Context menu	Right-click any bookmark: New tab, Same tab, Edit
Persistent state	Expanded folders and scroll position are remembered across popup opens
Bundle Filter	Filter the tree to show only bookmarks from specific linkding bundles
Manifest V3	Updated to MV3 for compatibility with current Chrome/Edge versions

Screenshots

Bookmark Tree

The popup opens directly with the bookmark tree — organized by tags, with favicons and tree connectors.

Settings

Configure your linkding server URL, API token, and optional bundle filter.

Where to find the API token

The API token can be found in your linkding installation under Settings → Integrations.

Installation

Load unpacked (development / testing)

1. Clone or download this repository
2. Install dependencies: npm install
3. Build: npm run build
4. Open chrome://extensions/ (or edge://extensions/)
5. Enable Developer mode
6. Click Load unpacked → select the project folder

After code changes, run npm run build again and click Reload in the extensions page.
Use npm run dev to auto-rebuild on every file change.

Firefox

Load via about:debugging → Load Temporary Add-on → select manifest.json.

Note: This extension uses Manifest V3, which requires Chrome 119+ or a compatible browser.

Configuration

Open the extension options (gear icon in the popup header):

Setting	Description
Base URL	URL of your linkding installation, without trailing slash
API Token	Found on your linkding Settings page
Default Tags	Tags pre-filled when adding a new bookmark
Bundle Filter	Comma-separated bundle names to filter the tree (see below)
Pre-select unread	Mark new bookmarks as unread by default
Pre-select share	Mark new bookmarks as shared by default
Use browser metadata	Use the browser tab's title/description instead of fetching from server
Pre-load page info	Pre-fetch bookmark status while browsing (shows starred icon on bookmarked pages)
Close popup after save	Automatically close the popup after saving a bookmark

Bundle Filter

linkding supports bundles — saved filter presets that group bookmarks by tags, search terms, or a combination. The Bundle Filter setting limits the bookmark tree to only show bookmarks belonging to the specified bundles.

Example: If you have bundles named Work and Programming, enter:

Work, Programming

The tree will then only show bookmarks from either bundle. The tag folders are derived directly from those bookmarks — no extra API call needed. Leaving the field empty shows all bookmarks (default behaviour).

Bundles are managed in your linkding web interface under Settings → Bundles.

Requires linkding v1.24 or later.

Development

# Install dependencies
npm install

# Build once
npm run build

# Watch mode — rebuilds on every file change
npm run dev
