730227 - on Linux, mouse right-click not handled in javascript for context menu, but always brings up Firefox system menu

Status: RESOLVED DUPLICATE of bug 693167

(Firefox :: Untriaged, defect)

Description

[St Heine]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
Build ID: 20120215223356

Steps to reproduce:

I'm trying to use a context-menu via javascript to be displayed on right-mouse-click, like the one on
http://medialize.github.com/jQuery-contextMenu/demo.html



Actual results:

on Windows, this works ok, bringing up the javascript-defined context menu.
on Linux, it brings up the javascript-defined context menu, but overlays that with the Firefox internal context menu (Back/ Forward/ Reload/ Stop/ Bookmark/ ...) and only on a second click I get to see the context menu defined in the webpage.


Expected results:

I expect Firefox on Linux to behave the same way as on Windows: when there is an app/webpage defined handling for the right-mouse-click, don't bring up the Firefox internal context menu.
