Following up on my last 2 posts (which are awaiting approval): Opening the 'here' link to this thread from Comment 15261648 in another thread in a new tab (by right clicking) and clicking on the new tab reliably crashes Opera, including 44.0.2510.1159, which I just updated to, and 44.0.2510.857. On a MacBookPro9,2 with 10.12.4 Beta (16E175b).
