I am using this addon on Firefox pre-57 and I am disturbed by one lack of option, in fact I use this addon for everything except the add-on taskbar. So I would like to have the button in the bar, except when I click on it it will open all the downloads in a new tab (while actually it will show a sort of pop-up that resumes the download, a sort of vertical pop-up).

So the question is how to enable the option to open the downloads in a new tab instead of a pop-up when clicking on the Download Manager button in the taskbar ??? Thank you
