<![CDATA[Open PDF files in the default PDF viewer application]]>Since the new Opera version (stable 44.x 64bit), the option "Open PDF files in the default PDF viewer application" doesn't work anymore, it just saves the pdf file without launching pdf viewer. I went back to 43.0.2442.1144 to have this option working again.

If yes, then the problem can be on pages sending wrong information about the PDF files to Opera.

I searched the forum and it seems many other people have the same problem. Opera does not open the PDF file but only shows a download dialog.

One was that Opera would download the pdf file to the temp_downloads folder (not the downloads folder) and then pass that path to the external application where that application would open it. The other was the "pass web address directly" option where Opera would just pass the URL directly to the application where the application would download it itself and open that download.

The OP said that Chromium Opera used to do one of those (the former I guessing, with the default pdf handler on the system, but the downloads folder instead of a temporary downloads folder or the temp folder), but it stopped working after Opera 43. Now Opera just downloads the pdf file and you manually have to launch the pdf file from your downloads folder or Opera's downloads dialog. As in, it quit being automatic.

It looks like Opera's current behavior is Chromium's intended behavior and there's nothing we can do about it except add a suggestion that Opera implement some modifications of the Chromium code/setting to optionally make it work like it use to.

BTW, there is no way to do nothing with a file on any program without downloading the file first to your computer,

If that's the case then I'm going to uninstall. That would be absolutely ridicuous to not have that option.

Opera doesn't support opening files directly if this is what you are talking about. You can however request it in the proper section of the forum or even better support one of the probably already created ones.

I was looking for a new browser and Opera was looking very promising... until I stumbled across this glitch. Really? Not being able to open PDF files in my computer's default PDF viewer program is unacceptable!

Temporary workaround (or maybe definitive because this issue was not taken into account): double click the pdf files on download drop-down list.

When you have "Open PDF files in the default PDF viewer application" checked and in your computer setting setup the default PDF app you want to use - Mine will open Adobe Acrobat Pro

Which Opera version have you installed?

"This is currently the intended behavior unless you check the automatically open this file type (from the download bar right of the filename). It used to open them automatically but we considered this to be rather intrusive."

It would take such an option even on Opera.

Could it be Chromium's fault? Because in 57 (and even 59) it's the same story.

If it happens in Chrome and other Chromium based browsers then, yes, it can be a Chromium issue.
