https://connect.mozilla.org/t5/discussions/firefox-spawns-a-printer-dialog-box-when-downloading-a-csv-file/m-p/121653#M47801 <P>I am using both the Firefox App in Windows 11 and Firefox Portable App (both are the most recent versions). When I download stock information from Yahoo Finance which is a CSV file, in either version, it always opens a Printer Dialog box in addition to the CSV download dialog box.&nbsp; And Firefox doesn't give you a way to add the CSV file type in Settings, Files and Applications to tell Firefox what to do when you download a CSV file. I'm aware this might be a quirk on the server side of Yahoo Finance, but am hoping a change can be made to Firefox to overcome this frustrating behavior.</P> Wed, 01 Apr 2026 02:47:21 GMT mireally 2026-04-01T02:47:21Z https://connect.mozilla.org/t5/discussions/firefox-spawns-a-printer-dialog-box-when-downloading-a-csv-file/m-p/121653#M47801 <P>I am using both the Firefox App in Windows 11 and Firefox Portable App (both are the most recent versions).
