854401 - site should be able to request permission for oncontextmenu.event.preventDefault

Status: NEW

Description

[John Drinkwater (:beta)]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:21.0) Gecko/20130323 Firefox/21.0
Build ID: 20130323042013

Steps to reproduce:

Visited http://codepen.io/stuffit/pen/KrAwx
Right click is used on the canvas in the example, the context menu currently gets in the way.

Google Maps, Youtube’s HTML5 video player and other sites have the same UX issue with Firefox’s context menu overlapping their custom menu. 
Until HTML5’s <section contextmenu=""> becomes popular, this will still be a problem for desktop users…

On first calling event.preventDefault inside oncontextmenu, a doorhanger permission could ask the user for permission to allow this for the site.

Firefox' Menu get's properly disabled over here (Win 7 x64).
Do you have dom.event.contextmenu.enabled;false set?

I do, forgot to mention this is more of a feature request for the future when/if Bug 851702 removes the advanced js options. Sites cannot go fullscreen without permission, and I have the same expectation for browser chrome.

This works fine with dom.event.contextmenu.enabled=TRUE on Aurora 21.0a2 (2013-04-01).

John means the user should be able to decide whether to allow the current site to disable the menu, e.g., for the session only.

And if the user refuses, the site should not know the user called the local menu, so as not cause confusing events like two menus over each other or a video being (un)paused accidentally.

[Florian Bender]

Websites should use HTML5 context menus (though some issues need to be fixed before they are particularly useful, especially Bug 705292 and Bug 897102). This preempts the need for adding a Firefox-only API which nags the user unnecessarily.
