v1.0.4

Binds Ctrl+Cmd+F to toggle fullscreen on the Zotero main window.

Install

Download zotero-fullscreen.xpi below, then in Zotero:
Tools → Plugins → gear icon → Install Plugin From File…, and restart Zotero.

Why

Zotero ships no native fullscreen on macOS. Its own titlebar code calls BrowserFullScreen(), which is defined nowhere in either omni.ja archive, so the green traffic-light button and the macOS-injected "Enter Full Screen" menu item are both inert. Zotero additionally rewrites NSFullScreenMenuItemEverywhere to 0 on every quit.

The underlying Gecko property works fine, so this plugin binds a key to it.

Tested on Zotero 9.0.6 / macOS.
