Mozilla Support site issues (mobile)
Firstly, if I go to look up a user's profile page and checking on one's posts/questions history located under the text "contribution" via Firefox mobile, all I saw is a search page with a blank result, unlike the desktop page which correctly shows results.
Secondly, the pulldown bar under the forum mobile page never worked on my mobile Firefox browser.
Both issues can be reproduced after a cookie clean up.

More details on the pulldown bar: in my case the bar handle portion correctly displays just below title bar on the forum topic list page, but show no responce under every kinds of finger swiping motion.
