I'm not sure about auto-open, but if you want it to prompt you before saving a file, go to Settings > Advanced > (scroll to Downloads) > "Ask where to save each file before downloading"

For auto-open, in Settings > Content Settings > PDF document, you can toggle the "Download PDF files instead of automatically opening them in Chrome" setting.

arrentan@ Thanks for the issue.

Request you to retry the issue as per comment #2 & #3 and update the thread with the observations.

Thanks..

It is not working. No matter what settings I have configured on the Google Chrome. I have tried everything.

The PDF file still auto open on my Mac's app named "Preview" (mark my words, not in Chrome browse) after I clicked to download the PDF.

I need the "clear auto-open button".

Thank you for providing more feedback. Adding the requester to the cc list.

Hi,

It happened after I clicked the "Always Open With System Viewer".

[image: Screen Shot 2018-06-12 at 6.55.40 PM.png]
 From then onwards, all of my PDF files will auto open on my System Viewer
"Preview". I need to revert this setting back to default. I don't wan to
auto open system viewer.

Btw, I am using Google Canary to take this screenshot. I am forced to use
Google Canary right now.

arrentan@ Thanks for the update.

Able to reproduce this issue on Windows 10, Mac OS 10.13.5 and Ubuntu 14.04 on the reported version 67.0.3396.79 and the latest Canary 69.0.3457.0 by following the below steps.

1. Launched Chrome and downloaded a file.
2. From the download bar menu, selected the "Always open with System Viewer" option.
3. while trying to open the downloaded file, it is opening with the system viewer, but once the download bar is closed, there is no way to uncheck the option "Always open with System Viewer".
Attached is the screen cast for reference.

This is a Non-Regression issue as this behavior is observed from M-60 chrome builds.

Hence marking this as Untriaged for further updates from Dev.

Thanks..

For my settings, the auto open will open on my Preview directly instead of on browser. 

Meaning that after I click a click to download the PDF, the PDF will auto open on my Mac's system "Preview" instead of asking me where to save the file.

Here is the short version of the file I download from my webmail.

Adding the conops hotlist for tracking.

Hi, we're using Chrome 67.0.3396.87 (Official Build) (64-bit) in our enterprise, and users are reporting the same issue. We've reproduced this exact issue on Windows 10, 1709.

We managed to resolve this issue by deleting our Chrome UserData folder:

C:\Users\tbrown\AppData\Local\Google\Chrome\User Data

I am using Mac. Any idea?

There is probably a Chrome folder in the /library system folder on macOS.

Got it sorted after deleted the whole Google Chrome file in the library.

It should not have be such as hassle if the button of Clear Auto Open still there.

arrentan@, have a look at https://productforums.google.com/d/msg/chrome/7mZxGSFpxMY/xd7qHzpgBgAJ (still kind of a hassle, but not as invasive as deleting your settings or creating a new profile)

I can't access 853734. Is there a public place to track this bug now?
