"Open in new tab" with ctrl+click is not working anymore on this forum

I couldn’t find the right forum so posting it here (admins are free to move it to the right place).
Recently for some reason “Open in new tab” with ctrl+click stopped working on this forum for me. It works OK on other websites. I’m using Firefox 47 and behavior is the same both under Windows 10 and Ubuntu 15.10. Does anyone else have this problem?

Yes, you are not the only one.

It seems it works OK now, many thanks to the admins.
