This might be a Firefox problem. I have never seen it before, but today I have seen it in 3 or 4 sites linked from HN. What has worked for me is to click "Accept all", then, after the pop-up reappears, click "Only necessary", which makes the pop-up disappear. Clicking "Only necessary" without clicking before that "Accept all" has not worked. Likewise, clicking multiple times one of those options has not worked.
