You need to specify an archive file with the f flag, e.g.

$ tar cf dpchrist-thunderbird-20170618.tar .thunderbird 

Traditionally, if no archive file is specified, tar(1) accesses a
tape device by default.  FreeBSD's tar maintains this behavior and
the FreeBSD port of gtar matches this for consistency.

Use "-" as archive name if you want to read from stdin / write to
stdout.
