Is your setting correctly set under Preferences - Applications or not? If your setting is forgotten after Firefox is restarted, see the following article. * [[How to fix preferences that won't save]] If the setting is remembered but it simply doesn't work, # Some file types have multiple MIME types associated with them. All entries must be set accordingly under Preferences - Applications. # The sever may be sending the generic ''Content-Type: application/octet-stream'' MIME type. # The server may be sending the ''Content-Disposition: attachment'' header. You can check the ''Content-Type'' and ''Content-Disposition'' headers by examining the response headers using the Web Console. Press Command+Alt+K to open it, then click the download link. In the web console, click the GET request for the file in question. For more details, see the following article. * https://developer.mozilla.org/en-US/docs/Tools/Web_Console If the download link is publicly accessible, you can just post it here and someone will have a look at the headers for you. ---- If the problem is the ''Content-Disposition: attachment'' header, install the InlineDisposition add-on. * https://addons.mozilla.org/firefox/addon/inlinedisposition/ If the problem is the ''Content-Type: application/octet-stream'' header, you can correct it with the Force Content-Type add-on. * https://addons.mozilla.org/firefox/addon/force-content-type/ URL: '''(.qfx)$''' Old Content-Type: '''application/octet-stream''' New Content-Type: '''application/x-qfx'''
