How can I enter the full path where to store or from where to load an attachment rather than mouse-click through all directories to the file I mean? On Xubuntu 16.04.1 Thunderbird‘s dialog when designating a file as an attachmentis 100% GUI oriented, i.e. I have to mouse-click all the way to the file to be attached. But often I have an Thunar open in the folder of my file to be attached. Ctl-c on that puts the full path to it on the clipboard – ready to be used in the dialog what file to attach. But alas, there is no more a chance to just paste the full path into TB. Also I can‘t just drop the file to be attached on TB!
