each time I save a file with firefox and click on ‘display progress of ongoing downloads’ on the top right part of the browser and click to open the containing directory, debian opens the directory, but in a new tunar window, not in a new tab in a pre existing thunar window.
It’s tiring working with so many open windows. Better one window and several tabs.
Firefox won’t be able to do this without Thunar supporting it, but someone else already posted that Thunar does support it.
