ZoteroQuickLook

This open source project implements QuickLook in Zotero.

Installing

To install ZoteroQuickLook, download the latest version of zoteroquicklook.xpi from the Releases section of this GitHub repo. In Zotero (not in Firefox), open Tools -> Add-ons. Then drag the zoteroquicklook.xpi file onto the Zotero Add-ons window.

Installing on Mac

On Mac, ZoteroQuickLook uses macOS's native QuickLook functionality. No additional steps are needed.

Installing on Linux

On Linux, you must install Gloobus-Preview, a QuickLook-like preview software. On Ubuntu you can do this by running the following commands in terminal:

sudo add-apt-repository ppa:gloobus-dev/gloobus-preview
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install gloobus-preview

For other distributions and versions the installation might be different.

If you do not like Gloobus, you can define a custom QuickLook command:

1. Install the software you want to use for previewing files. The software must be able to take a file name as a command line parameter.
2. Open the Config Editor in Zotero's Advanced preferences pane.
3. Search for extensions.zoteroquicklook.customviewcommand. Set the value for this config to the full path of the executable that you want to use to show the files.

Installing on Windows

On Windows, you must first install a QuickLook tool. By default, ZoteroQuickLook is set up to work with QuickLook. Note that you must install QuickLook using either the .msi installer or through the Windows Store. If you use the .zip version of QuickLook, you must also set up a custom view command.

Alternative QuickLook tools for Windows include Seer, WinQuickLook, and the paid software MaComfort. In my experience, the default option, QuickLook, is the most stable and powerful and least resource intensive option. You can choose another QuickLook program if you like. The software must be able to take a file name as a command line parameter.

After installing a QuickLook program, set ZoteroQuickLook to use this program:

1. Open the Config Editor in Zotero's Advanced preferences pane.
2. Search for extensions.zoteroquicklook.customviewcommand. Set the value for this config to the full path of the executable that you want to use to show the files.

Alternative build for Windows

Installing the extension on Windows sometimes fails with the error message: "ZoteroQuickLook cannot be installed because Zotero cannot modify the needed file." This is a Windows specific problem caused by the 256 character filename length limitation. This limit is reached during unpacking the xpi archive when installing the extension. Mozilla has fixed the issue by eliminating unpacking of extensions by default and running them directly from the xpi archive. However, this solution does not work for ZoteroQuickLook because on Mac and Linux, the extension uses executable files that need to be unpacked so that they can be run. These files are not used on Windows and there is a parallel version of ZoteroQuickLook that supports running directly from the xpi file. This version is called zoteroquicklook-windows.xpi and is available from the Releases section of this GitHub repo.

You can read more about the problem on Stack Overflow and the pages linked to from there.
