Yeah - I can confirm this. I don't know how to fix it though - Firefox
and Chrome just render these data list elements differently. You can
disable the drop down arrow in Chrome - but not enable it Firefox -
and I like the default Chrome behavior better :(. I guess the correct
thing to do here is
In the workflow editor, if you add an Input dataset collection, the
Collection Type: shows list. No dropdown arrow appears using Firefox. A
dropdown arrow appears when you mouse over using Chrome.
In Firefox, if you mouse over where the dropdown box should be, you can
still click to choose list
