 Replying to [comment:8 gk]:

 Blocked:"-message.
 When redirect in comment:11 transforms into an endless loop, maybe,
 because of #18222, the message isn't shown in Console too. But it appears
 only once in the loop after clicking Clear, and 403 Forbidden isn't shown
 at all after it, probably, because of #19921. So, this all looks like
 previous craziness of Torbutton.
