Since v60, when I try and email a file using the right click/send to command, nothing happens - nothing. I did get a warning that 'another program is trying to send mail, do you wish to proceed' msg, but whether I clicked on yes or no, still no email window appeared. I then clicked in the check box of 'do not show this error msg next time', so now I don't get that msg, but still nothing happens. I'm using v60.5.2 - 32bit. Firefox v65.0.2 64bit.
