cannot confirm addon instalation
When I choose "add to firefox" in addon installation, a dialog window - or bubble originating in the address bar - appears with choices Cancel or Add. But neither choice reacts to mouse click or positioning cursor and pressing enter, neither to pressing underscored first letter.
