Created attachment 807156 [details] iframe_bugtest.html User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release) Build ID: 20130814063812 Steps to reproduce: HTML 5 page has a link and iframe with some content (external page). I browsed the page inside iframe - clicked on links, selected text etc. Then I clicked the link outside iframe quickly - moved cursor above the link and clicked without any delay. iframe_bugtest.html is attached to bug report for demonstration Actual results: For about 1-2 seconds after moving mouse over the link outside iframe mouse down/click events are not fired at all after a click. When user waits and then clicks, the mouse down/click event will be fired. The same with mouse up event. Mouse over event works fine immediately. This problem occurs only when <!DOCTYPE HTML> is used (HTML5) and when the html page is hosted in some web container (like Tomcat). apache-tomcat-7.0.32 was used with standard configuration and only single html file in root web context. If <!DOCTYPE HTML> is not used, then mouse down/up/click events work immediately. If html page is loaded directly from disk, events work correctly even if <!DOCTYPE HTML> is used. Expected results: Mouse up/down/click events should be fired immediately when user moves outside of iframe and clicks on link. In IE 9.0.8112.16421 and Chrome 29.0.1547.66 it works as expected.

Still an Issue? I see no Issues clicking the link and counting to happen.
Hello Reporter, thank for reporting this issue. I tried duplicating this problem on the latest released version of Firefox (43.0.4) by navigating to the HTML page (that you attached) installed on Apache Tomcat 7.0.67 but did not see the problem that you observed. Mouse click performed as expected and the counter increased right away. I tried on Windows 7 64 bit machine using: Name Firefox Version 43.0.4 Build ID 20160105164030 Update Channel release User Agent Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 If you have not upgraded so far, may I request you to try again on the latest FF version and let us know if you still see the problem.
