I would consider this bug critical. The world is not only PDF documents. My wife uses the Citrix Receiver for home office work. This application relies on configuration files being downloaded and opened by the receiver application. This won't work with the current Firefox, and setting this up in Chromium was a pain.

Starting with the update, all downloads fail. There is no file selection dialogue any more, just the blue arrow appears - and the downloads list says "Failed". I have tried the same on a clean profile with no add-ons, and downloads still fail. In the browser console, I get the following error message on each download attempt: [Exception...

Result: Blue arrow appears, downloads list says "failed" below the download filename. The file will not download. Expected result: File dialogue (with appropriate settings).
