Disable viewing PDF files directly in web browser (IE and Firefox)

Adobe Acrobat also comes with Internet Explorer and Firefox plugin which makes it take over PDF files downloaded via browser and display them directly in the browser.

This is not always a desired behaviour and you can use Sumatra as the default PDF viewer in both IE and Firefox, without completely uninstalling Adobe Acrobat.

Here are the steps (based on this blog post):

  • Launch Adobe Acrobat
  • Select Edit/Preferences
  • Select Internet
  • Uncheck Display PDF in browser
  • Click OK
  • Launch Sumatra PDF viewer
  • Select menu Setting/Options... and click "Make SumatraPDF my main PDF reader" button

Clicking on links to PDF documents should no longer open the embedded viewer but pop up a dialog box. Select "Always perform this action..." checkbox if you want Sumatra to automatically open those PDF files.
