Hi, when i search manually updates for my extensions, it search, search and search and find nothing( so it never say no updates available) since 3 or 5 days!! But when i search manually with this function, it find well userstyles for stylish, so it wont work only for extensions, last day i've update an extension on FF addon site, cause, the button haevt found it, of course!!

btw: when i search manually: it only say: search update and never: no update, when i push to search: it never stop to search, in fact it's like the service of FF center never heard it, but i know that it works with my friends, so...!!!
