User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/16.0 Firefox/16.0 Build ID: 20120726042008 Steps to reproduce: For a page with survey, that has sections are hidden/shown. A previously hidden section, was revealed with <select> boxes. Actual results: The dropdown of the select shows only 1 option, usually the first option "choose". The other options can be still picked by using the arrow keys and the mouse wheel. This behaviour happens with a Firebug window open, in the given example attachment. But for the full page the attachment was based on, it happens even with add-ons disabled. I have not been able to reproduce this with very simplified versions of the same things. Which leads me to conclude there must be something with memory that's affecting how the <select>'s dropdowns are being rendered. Expected results: The <select> dropdown shows all the options it can reasonably display on a screen.

Summary: <select> dropdown box doesn't expand beyond 1 option → <select> dropdown box doesn't expand beyond 1 option on redraw
This seems to only happen on redraw, as <select> boxes that appear right away when the page is loaded will always be fine. It's ones that are hidden and then made visible.

I had this bug trigger on my website, so I've created a minimal testcase for the problem as seen on 16.0a2. Refresh while scrolled to the top for an intact list; refresh while scrolled to the bottom for a list with only one item.

This is a regression since 14.0.1 and 15.0b2 both work correctly.

This seems to be fixed on the latest Nightly build (was fixed this week I think).

This video shows this bug in action, and how it's just Firefox 16: http://www.youtube.com/watch?v=OufMGLGZAls&feature=youtu.be Seriously though folks, as Firefox has auto-updates enabled by default this kind of bug is simply unacceptable. SLOW DOWN guys, you're breaking things.
