I know that there is an issue with the exact same topic. Unfortunately this issue does not solve my problem and I cannot get an answer by posting there, so here is a new issue
mail address - link setting - mail address => always opens new tab AND the mail program
mail address - link setting - external url "mailto:firstname.lastname@example.org" => always opens a new tab AND the mail program
I want to tab NOT to open but only the mail program
Moreover there is no checkbox "open in new tab" to check or uncheck.
Please help me out!
