Same for me here.

i got that info upon installing 10.9 as well.

thanks for hint for the pref pane in the incompatible folder. it did work after installing it again.

but i noticed now this…and i dont know if its due to maverick or if it is older:

in the webrep : it says in google chrome the module is installed and is fine.
for firefox and safari, its says it needs to be activated respctiuvely there… but i dont see a place where i can do it.
