Troubleshooting: Some PDFs are not opened by Firefox

Symptom

When opening some PDFs from the Internet, the Mozilla Firefox browser opens a new window or tab, but fails to display the PDF contents.

Problem

This can be due to a malfunction of the mozplugger Firefox component.

Solution

Disable mozplugger. Firefox will download the PDF document and open it with a local application (IGEL Linux 5.07.100 or newer):

  1. Go to System > Registry in IGEL Setup.

  2. Use Search Parameter ... to find the parameter browserglobal.app.dom_ipc_plugins_enabled_mozplugger_so.

  3. Check Completely disable mozplugger.

  4. Confirm the setting with Apply or OK.

  5. Restart Firefox.
