I am installing on Firefox the 2 certificates used in Spain to deal with the government. This video https://youtu.be/uePxWRjCY_o?t=322 on 5:23 shows how the Servers tab has an "Import..." button. The procedure the video follows is this: - First they import an authority certificate in the Authorities tab, there is Import button. -Then the video installs the servers certificate, in the video there is "Import..." button there, but not on any of my 3 computers running Xubuntu 16.04 64bits fully updated. Do anyone knows what could be happening? Thanks in advance.
