Observed behavior

Understand and Manage Tabbed Viewing Behavior

This prompt is normal behavior for Acrobat's tabbed viewing mode to prevent the accidental closure of multiple documents at once.

When you use tabbed viewing and have multiple PDF files open, closing the main application window triggers a safeguard prompt. This prompt asks whether you want to close the active document or all open documents. No changes need to be made to the files for this prompt to appear.

1
Identify the closing prompt

Click the 'X' in the top right corner of Acrobat. A dialog box will appear asking 'Do you want to close all tabs or the current tab?'.

2
Choose your closing preference

Select 'Close All' to shut down the application completely, or 'Close Current' to close only the active PDF while keeping the others open.

3
Disable the prompt (Optional)

If you find this prompt annoying, check the box that says 'Always close all tabs' on the dialog prompt before clicking 'Close All'. Acrobat will remember this preference for future sessions.

Frequently Asked Questions

Can I open PDFs in separate windows instead of tabs in Acrobat?

Yes. Go to Edit > Preferences > General. Uncheck the option that says 'Open documents as new tabs in the same window'. This will force each PDF to open in its own separate application window.

Why does Acrobat ask to save changes to a PDF when I didn't edit it?

Sometimes Acrobat silently updates file metadata, repairs a corrupted structure, or handles embedded fonts in the background when the file is opened. This background processing counts as a 'change', prompting the save dialog upon closing.

How do I bring back the 'close all tabs' prompt if I previously checked 'Always close all tabs'?

To restore the prompt, navigate to Edit > Preferences > General, and check the box for 'Prompt before closing all tabs'. Click OK to save your changes.
