When trying to select a value in a drop down in Service Now, the drop down is slow to display and control.  It will often open and close and not allow me to choose an option from the list.   I often have to get around this by using my down arrow on my keyboard to select the value.
Could you provide steps to get to one of these dropdowns? The selectboxes I get in, say, https://mozilla.service-now.com/sp?id=sc_cat_item&sys_id=e3b696fe0fc66600f67ab65be1050e96 , look different, but I don't know how to get to the page in your screenshot (and even if I could, with whatever privileges I get on service-now (not really any, AFAICT! :-) ).

Do we have control over the servicenow vendor / software? Does it work better in another browser (Edge/Chrome/Safari) ?

The dropdowns are in the fullfiller view - to which I don't think you have access, but i can give you access in our dev server.

We have some control, but that's dropdown is core feature and we don't have much control over it. The same drop down behaves correctly in Chrome and Safari.

OK. Does it work in Firefox release (I'm assuming you're using Nightly)? If so, could you use mozregression ( https://mozilla.github.io/mozregression/ ) to narrow down when it broke?

I am using nightly on a Macbook - OS 10.11.6.   I tried in FF54, and there's similar behavior, but the lag and inability to control is more pronounced in Nightly.  I tried to install the mozregression, but I seem to have all kind of errors.

Not sure if this matters, but my coworker is on OS 10.12 and he's experiencing the same issue but his is less noticeable than on my machine. In his FF54 - it's barely noticeable.
Out of curiosity, if you go to about:config and flip dom.forms.select.customstyling to false, and restart Firefox, does the problem lessen?

Yay! - updated that to false, and it does make it much better. There's still a little bit of a lag, but it's not frustrating like it was before.

Doesn't sound like this is critical enough that we'd take a late-breaking fix for it on 57beta (particularly since its severity is variable, per comment 5).  --> firefox57:wontfix

And ideally, we need to come up with a testcase (or some generally-accessible page) before we can usefully proceed here, I think... --> testcase-wanted

If this is still reproducible, can we get a Gecko Profile of this case?

Sure, how do I do that?
