Hi Martini, Ah ok. I'm not going to investigate further, but I didn't see any JavaScript requests when I clicked that link. So my best guess (and something to think about for anyone else looking into this for the sheer mystery of it) is that it is something at the protocol layer. That is, maybe some Wikipedia servers started speaking HTTP/2, or changed their HTTP implementation, and the old version of Firefox doesn't understand it and re-requests the URL many times in succession. Just a wild guess.
