Yes, that part is already done, but in previous versions it showed , when files with .data, . bd, .doc , img format were downloaded, what you mention is only active for the list of files that is shown there(https://support.mozilla.org/es/kb/Administr...
You are absolutely right, the download is temporary and it is much more efficient to work. Thanks for your contribution, it was a solution, but we need you to allow us to decide, "what we should do with each type of file", as it happened before
I am using version 100 and this problem still continues, it only allows me to choose between a few file types, but a .data or .doc extension saves them automatically
