I am running Linux with Firefox. When I select the 'more' icon (three dots) in the posting, it shows a rounded orange box around the dots, but nothing happens. Couldn't find a solution in the support postings. What am I doing wrong? TY
I'm pretty sure that button isn't a dropdown menu, it just toggles showing other buttons next to it if they're hidden. If you make your browser window really narrow when viewing a list of posts (narrow enough it goes to the mobile view), you can see pressing that button toggles showing the block and report buttons, which would normally show up. So I don't think you're missing anything, I think it just doesn't hide the button when it does nothing.
On an instance running 0.18.0 it's actually a dropdown, and it just shows those two buttons in it.
