Created attachment 801228 [details] stopPropogation.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: Left click/right click the link in the attached document. Actual results: In the attached html, right clicking the link is detected by the document element as a click + contextmenu event. This happens in both firefox v23.0.1 and nightly 2013-09-07 Expected results: I've also tested this in chrome, which has the correct behavior of the right click only being detected as a context menu event.
It happens in old versions like FF8.
I think this is dupe of Bug 569071
