When I try to download any file a confirmation dialog appears (see attached file). I don't need it. Its quite annoying. I just need to download a file without any confirmations. How to disable this behaviour? As you see there is no no checkbox "Do not ask me again..." or "Always perform this action when handling files of this type" in this dialog. I also set up option "browser.download.forbid_open_with" to true in about:config but it doesn't help. I need to start downloading immediately after opening a link to exe-file (this one for example): https://www.win-rar.com/postdownload.html?&L=4&f=winrar-x64-561am.exe&spV=true
