Created attachment 8372732 [details] Gear icon popdown menu User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release) Build ID: 20140205162153 Steps to reproduce: When I open Gmail (mail.google.com), and click on the Gear icon button, it shows a popdown menu of display density, etc. Actual results: When I started to hover on the list, Firefox goes not responding. Expected results: When I start to hover on the list, it should hover instead of going not responding.
Same for me. Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0) Gecko/20100101 Firefox/30.0 BuildID: 20140208030207
Additional information: I have tried on a new Firefox profile and on Firefox safe mode, same results happened: Firefox goes not responding indefinitely.
