I have Firefox 52.0a2 (2017-01-14) (64-bit) on Windows 8.1 64-bit and DTA 3.0.8.
When I download anything using DTA, all works fine. But when I try download any file from any site using Firefox it cann't download anything. In other words I click on file link and I see windows that suggests me to select if I want open file, save it or download using DTA or DTA.click. I select "save file" but no file downloading. I look at download hystory in Firefox and see that donloading was canceled.
How can I fix it?
