How to Restore the Open or Save PDF Prompt in Mozilla Thunderbird
Question details
The user wants to restore the prompt that asks whether to open or save a PDF attachment in Mozilla Thunderbird.
- Product
- Mozilla Thunderbird
- Device & OS
- not provided
- Scenario
- Clicking on a PDF email attachment within Mozilla Thunderbird.
- Observed behavior
- Thunderbird defaults to saving PDF attachments automatically without offering the prompt to open them directly.
Ensure your Mozilla Thunderbird application is updated to the latest version so that the settings interface matches the standard troubleshooting steps.
Adjust Thunderbird File Handling Preferences
Modifying the default action for PDF files within Thunderbird's settings is the most direct way to restore the missing prompt.
Thunderbird has an internal file handler that determines what to do with specific attachment types. If the 'Do this automatically' box was checked in the past, Thunderbird will skip the prompt. You can easily reverse this in the general settings.
Click on the application menu (the three horizontal lines) in the top-right corner of the Thunderbird window and select 'Settings' or 'Preferences'.
Scroll down the 'General' tab until you find the section labeled 'Files & Attachments'.
Look for 'Portable Document Format (PDF)' in the 'Content Type' column of the list.
Click the drop-down menu in the 'Action' column next to the PDF entry and change it to 'Always ask' or 'Ask whether to open or save'.
Reset the Application Handlers File
If modifying the settings menu does not work, resetting Thunderbird's handler preferences will force it to ask you how to handle PDFs again.
Effortlessly Open and Read PDF Attachments with WPS Office
Make handling PDF email attachments a breeze by pairing Thunderbird with WPS Office. WPS provides a fast, lightweight, and feature-rich PDF reader to view, annotate, and manage your documents seamlessly.
- 1. Download WPS Office: Install WPS Office for free from the official website to access the built-in PDF reader.
- 2. Set as Default PDF Reader: Open your computer's system settings and set WPS Office as the default application for viewing PDF files.
- 3. Open from Thunderbird: When Thunderbird prompts you to open the attachment, select WPS Office to enjoy a seamless and fast reading experience.
Frequently Asked Questions
Why did Thunderbird stop asking me what to do with PDF attachments?
This usually happens if you previously selected 'Do this automatically for files like this from now on' when downloading a PDF. This action saves your choice and bypasses the Open or Save prompt for all future PDF attachments.
How do I change the default PDF viewer that opens from Thunderbird?
Navigate to Thunderbird's General Settings, scroll to the Files & Attachments section, locate the PDF file type, and change the action to 'Use [Your Preferred Application]' by browsing for its executable file.
Will resetting Thunderbird's settings affect my saved emails?
No, adjusting the Files & Attachments preferences or renaming the handlers.json file only resets how Thunderbird interacts with external file types. Your emails, accounts, and server configurations remain perfectly safe.
Why doesn't Adobe Acrobat control this setting?
How email attachments are handled initially is determined by the email client (Thunderbird). Once you choose to open the file, Thunderbird passes the document to your default PDF viewer (like Acrobat or WPS Office), which is why the setting must be changed within Thunderbird itself.
