1417456 - Shift-F10's context menu cannot be suppressed by web app

Status: RESOLVED DUPLICATE of bug 1338369

(Core :: DOM: Events, defect)

Description

[Jonathan.Brink]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20171024165158

Steps to reproduce:

Please see this StackOverflow question for a full summary of the issue.

What I did was to listen to when the shift-f10 key combination is pressed, and try to prevent the browser context menu from appearing.

None of these seem to work:
  e.preventDefault();
  e.stopPropagation();
  e.stopImmediatePropagation();


Actual results:

The browser context menu still appears


Expected results:

The browser context menu should be suppressed.

This sounds a duplicate of bug 1347079, right?

No. Bug 1347079 is, users cannot forcibly open context menu with Shift+F10 on Windows and Linux. This bug reports is, web apps cannot prevent context menu to open when user types Shift+F10.

This bug is dup of bug 1338369 which was fixed on 56. And then, if user cannot mouse nor context menu key of 109 keyboard, users cannot open context menu without F10 key with any modifiers.

Oops, that was fixed on 55.
