Firefox 78+ releases offer a choice to open PDF files that would normally be saved or opened in an external application in a Firefox tab (Open in Firefox).

This feature is controlled by prefs on the about:config page that are enabled (true) by default.

  • browser.helperApps.showOpenOptionForPdfJS
  • pdfjs.handleOctetStream

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".

有幫助嗎?
