Yes thanks! realized myselves in same moment but it take some times before messages comes through the 'limestone'!

But nevertheless it does't work neither by this nor by removing the .mozilla map (even with filecase/box root deleting does not work, it says Deletion completed but nothing happens?). Still installation interrupted

OK restored N9 and then out of nowhere both Wazapp and Qmlbrowser now are updated!
Even if I still don't succeeded in removing the .mozilla, which I don't understand due to root access!?
