Display the Primo Normalized XML (PNX) for a record, from within the Primo end-user interface. From the full display of a record, right-hand click to display the Firefox menu which includes the option to “Look Up PNX”. Select this, and the PNX record will be displayed in a new window.
This code simply opens a new window, adding “&showPnx=true” to the URL of the page currently open, so it only works against Primo v2. It works fine in FF2, and FF3. Just drag the .xpi file into a Firefox window to install it.

We have problems with windows 7. The entry “Look up PNX” is not shown in the context menu. Has anyone tested this plugin for windows 7?

It is not a problem of the Windows version, but of the Firefox version. Even under Windows XP the plugin stops working once you upgrade to Firefox 3.6.x, which is a real pity. Pnxlookup is a really helpful tool and I got attached to it. Maybe Lee can provide an update?

  1. Lee:

    Is it possible to update and sign this Firefox add-on? It can no longer be used (unsigned).

    Thank you,
