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.

This is an issue dating back about 15 years. Sites are not supposed to have spaces in an unquoted filename when sending a download header and Mozilla decided not to follow other browsers that fill in the gap.

Can you suggest to the site that they fix it? It should be pretty easy for them, either by adding quotation marks around the file name or replacing spaces with underscores. There are plenty of recipes online: content-disposition filename spaces firefox site:stackoverflow.com - Google Search
