I am having issues with the newest version of Chrome. It's blocking downloads of PDF, and docx files from our site. Internally I can whitelist using chrome management but I can't do that for our customers who will need to download these types of files.
Is there something that I can fix? Im serving everything from HTTPS and there is no mixed content on the site. I'm using the send_blob() method provided by the blobstore_handlers.BlobstoreDownloadHandler.

Okay so it's not just an AppEngine issue - but man - this new Chrome Policy is crazy.

Note for anyone looking. This seems to be a Chrome Bug that affects Chrome for Mac and from the sounds of it Google is pushing some silent fixes as I am typing this. It's blocking content based on the extension and mime-type whereas it should be also considering the use of http:// and https:// on delivery. Not an app engine issue - thankfully. The blobstore is a bit of a blackhole now.

Thank you for the info. If the issue is indeed about the Google Chrome, you could reach out to the Chrome Community[1], perhaps there could be some help or workaround offered there.
