Logseq Quick Capture v2 v0.2.9
This supersedes the other version on Firefox Extensions as I lost the password to the account used to publish v1, hence needing to create a new submission.
Logseq is an open-source note-taking app (www.logseq.com). This extension allows you to do a quick capture of the web-page that you are currently at and send it immediately to your open Logseq graph.
It captures the URL and title of the page; and if you've made a selection, it would capture that as well.
