Hello I have noticed that I haven't been able to use some of js code that I import from this wiki for a long time although I have added them to my global JS page. For example, I no longer see any of Quick Tools box on users' contributions pages on my wiki although I still keep  on my global JS page. That also happens with AjaxDiff, when I can not quickly view diffs on pages when I'm opening the Special:RecentChanges without leaving the page. Please help, I don't know what happens. Maybe I have installed quite a lot on my JS pages? Thank you.
