User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170814072924
Steps to reproduce:
1) Open attached HTML file in browser
2) Try to select some option in <SELECT>
3) Observe reactions of UI
Actual results:
In Win Firefox 55.0.2 It is quite slow/lags or does not react on user interaction and sometimes it even stops responding on WIN
Expected results:
It should be like in Chrome or in Linux FF55 or previous FF54 version where everything is fast.
See attached video where it is clearly visible.

So I have tried current FF developer which is 56.0b3 and it seems that there it is okay in Win. Is there some difference between 55 and 56b in rendering <select>?
