Event delegation is once again failing in Facebook and AMO.This review is for a previous version of the add-on (2.1). This user has other reviews of this add-on.
It continues to work here like the first day, so... i guess there might be some conflict with some other add-on you've installed. Please try the just uploaded version 2.2.1 and let me know if the issue is gone.
