Menu app icon > 'Preferences' > 'General' 'Files & Attachments' section Content Type: HTML Document - What is set up as the Action ? Content Type : PDF - What is set up as the Action ?

Try setting the following, restart Thunderbird and report on what occurs. Content Type: "HTML Document" Action is usually a browser - "Use Firefox Web Browser (default)", changed it to "Always Ask" Content type: "Portable Document Format (PDF)" set Action : "Preview in Thunderbird"
