Open PDFs in an external application like Adobe Reader

  • Hi,

    opera://settings/?search=pdf

    • If the checkbox is not checked, Opera opens PDFs in the internal viewer.
    • If the checkbox is checked, Opera opens a save dialog.

    How can I make Opera to open PDF files in an external viewer application like Adobe Reader?

    Opera version information:

    • Version: 48.0.2685.50
    • System: Debian GNU/Linux 9 (stretch) (x86_64; XFCE)

    Br,

    Harri

  • You can't. That option is to bypass the internal PDF reader so you can download the file and open it in another reader.

  • You can't because chromium based browsers, opera included, do not allow opening files with an external app in general. E.g. you can not make it open a .doc with ms word directly. You have to save it first and then open it.
    Opening the file inside the browser is limited to what the browser can support natively, e.g pdf files, some multimedia ones like mp4 etc.

    However, they allow opening different protocol urls with external apps, e.g. magnet:// links will open with a torrent client when clicked, mailto:// ones will open with the email cleint etc.
