Expected results: opened menu.

Sorry, I don't understand why this is a bug. The web site intentionally prevents the context menu from appearing (by using preventDefault on the contextmenu event), and as far as I can tell this is working in Metro Firefox the same way it works in desktop Firefox and other browsers.

Oh, now I see -- the expected result is that the Metro Firefox toolbars should appear, but this does happen because the web site stops propagation of the contextmenu event. I thought we had an open bug about this, but I can't find it now...

Can we simply disable that feature for now? It's a user pref so I imagine it's not difficult to toggle and the upsid of the semi-useful web feature seem far outweighed by the downside of it breaking a fundamental Windows gesture. What does IE do here?

Thanks, Rodrigo. This may be difficult to solve. Given that IE's done nothing there and that we don't have an obvious solution in hand and given that the touch gesture is a solid workaround, I think we push this out to a later version.

A keyboard workaround is the shortcut win+z, which is the default shortcut for showing the app bar. Currently SHIFT+F10 and the keyboard context menu button have the same effect of showing the app bar, but that's probably a bug.

On desktop Firefox, shift+right-click always shows the browser's built-in context menu.

I hit this problem with Google Drive on Nightly 20131124.

The easiest solution is to make this event listener capture (change "false" to "true" on this line): http://hg.mozilla.org/mozilla-central/file/757c2011df5b/browser/metro/base/content/contenthandlers/ContextMenuHandler.js#l15 This would completely break the ability of web pages to receive or prevent "contextmenu" events, but based on comment 5 it sounds like we are willing to make that trade-off.
