It's a bug in Firefox, and affects the Windows version, not just Android. It's the worst sort of invisible and undiscoverable UI bug: clicking on the left/middle of the box is interpreted as wanting to do text input (with no menu of choices to select from), while clicking on the right end activates an apparently invisible "pull-down arrow" that will show you the list of allowable choices. Yuck!
