The custom event should have the following event detail: { detail: { filter: 'browser-only' }}

I changed it in both app_chrome and browser_context_menu, not sure both are required as only the latter is called currently (but I distinctly remember app chrome being called instead with the new style overflow menus).

Please investigate the failing unit test before landing, and request uplift to 2.1.

Failing test looks like a known intermittent but, I did rebase against the latest master. Hopefully everything passes this time. https://tbpl.mozilla.org/?rev=40be0348d7b087c0eeb62b01d8a1bd3a33fe4855&tree=Gaia-Try
