[Mozilla Enterprise] Streams Setting for Potentially Dangerous Files

[Eddie Rowe]

On Windows 10 when I download a PDF from our web server, it does not have the streams configured to indicate the file was downloaded from the internet.  But when I download from a non-company web site the streams info is saved by Firefox.  So PDFs from our servers are not consider dangerous, but ones from other sites are considered such.  Except that webmail is dangerous...  How does Firefox know our domain name to cause this behavior?  On IE there is the concept of zones, but I am not aware of Firefox having this setup.  I have reviewed the policies.json and the Mozilla.cfg and I do not see anywhere I have specified our domain for any special treatment, except for the pop-up blocker policy.

Streams is how Adobe Acrobat/Reader decides if a PDF is dangerous - I may not be calling it the right thing, but based on the tool from Microsoft being called Streams I think it is.  When you view the properties of a file there will be an "Unblock" checkbox for any file you download from the internet.  Acrobat knows when a file is opened by Firefox and passed to Acrobat that the file is potentially dangerous.)
