LinkAce Quick Save od Mike (ma2bdev)

LinkAce Quick Save is an unofficial companion extension for self-hosted LinkAce bookmark archives.

Features:

Save the current tab via LinkAce's REST API in one click, or with a keyboard shortcut
Title and description are pre-filled automatically from the page itself
Assign existing tags and lists from an autocomplete dropdown
Set link visibility (Public / Internal / Private)
Detects if the current page is already saved and lets you update it in place instead of creating a duplicate
Interface available in English and Spanish
Requires a LinkAce instance served over HTTPS and a personal API token (Profile → API Tokens in LinkAce). Your token and link data are only ever sent to the instance URL you configure — nothing is collected or sent anywhere else.
