Description Huzaifa S. Sidhpurwala 2016-01-26 04:16:03 UTC 
Security researcher window reported an issue where the protocol handler dialog appears, double click events are treated as two single click events. This was caused by the lack of a delay following the initial focus in the file download dialog. This could cause a second dialog to be sent the second click, leading to unintentional user initiated actions, such as the running of downloaded software from a maliciously positioned prompt.
