This was relayed to me from a Mac user, but I'm assuming the same problem occurs for anyone with a touch mouse or other input device with a sensitive scroll trigger. Currently, Firefox, when opening a |select| drop-down form control, will cancel the drop-down when a mouse scroll event is received *outside* of the drop-down pop-up. If there's a sensitive scroll event trigger, which is the case with most touch-mice, it becomes difficult and frustrating to use drop-down menus because they will close without making a selection due to the scroll event on the page. Chrome completely disables mouse scroll events on the page when a drop-down on a web page is open, avoiding this issue -- which would probably be the best behavior here (at the very least as an option) in Firefox as well. Let me know if the description is in any way unclear and I'll do my best to clarify.
