User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36 Steps to reproduce: Attempt to download or view a pdf file on a site that uses a Download.php file to control the downloading of files. Firefox renames the pdf file to Download.php, so it opens in a text editor instead of Adobe Acrobat, causing errors. This is not an issue with the same downloads and pdf files on either Microsoft Edge or Google Chrome. Actual results: File opens in text editor on OS X instead of Adobe Acrobat. Expected results: Download.php tells the browser to download the pdf file, pdf file should download with its proper name, and open in Adobe Acrobat.
