Downloaded Files, A generated PDF in particular, don't have the correct filename and are missing the extension.

I am downloading regularly a generated PDF file from a website. The file might be named something like "Quote UX151133.pdf" and when it downloads in Firefox it comes down as only "Quote". Both Chrome and IE download the file correctly.
