This open source project implements QuickLook in Zotero.
This is a fork of the excellent work done by @mronkko, @bwiernik, and others on ZoteroQuickLook.
I only use Zotero on macOS so support for Windows and Linux has been removed. If there is demand I can add it back or help interested parties open a Pull Request.
To install ZoteroQuickLook, download the latest version of
zoteroquicklook.xpi from the Releases section of this GitHub repo. In
Zotero open Tools -> Add-ons. Then drag the zoteroquicklook.xpi file onto
the Zotero Add-ons window.
