User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20160315153207 Steps to reproduce: Right click on the page, but before releasing the button, move the mouse over 2 pixels. (aka right click and start to move the move to the dropdown menu at the same time) Actual results: Back button was clicked Expected results: The right click menu should have opened. It appears a feature was added that allows you to hold down the right click button while opening the menu, and whichever option was selected, on mouseup, would trigger a click. However, this behavior is absolutely maddening when I am simply trying to open the menu to select an option in the list. I have always used Firefox by right clicking ( mousedown + mouseup ) and then selecting a menu option. Proposed solution: If rightclick mouseup happens within a certain number of milliseconds, don't trigger a click on the element and instead treat the down+up as a single "action" whose desired purposed was to open the context menu.
This is by design. Context menus in other applications like TextEdit.app and Calendar.app work the same way.
