(Note 4, Oneplus One, Nexus 5) Oneplus Two is running Oxygen OS 2.1 (Android 5.1.1 ROM) (The latest stable release) 1) Installed Firefox for Android on OnePlus Two (fresh install, new device) 2) Opened Application Actual results: 3) No sign of the Settings/Option button, just the 'Tab' button. Works fine 4) User cannot jump into the Settings/Option section. *screenshot attached Expected results: Settings/Option Button should appear on the UI.

Interesting. This almost looks like HardwareUtils.hasMenuButton() is returning true on this device.

The OnePlus Two has a Volume Rocker (akin to the iPhone/iPad setup). This is the only unique hardware feature I've not seen on other Android devices. Tested on all channels just now, same result.

It doesn't have the three dots, but if you long press the window key,it opens the options

Can confirm that the long press works. Is there anyway we can include this in the UX in the future? Otherwise (like me) users will be confused at first.

I just filed bug 1209967. We are considering always showing the overflow menu - No matter what the hardware is.

Thanks Sebastian for the follow up bug. As this is implemented through HW Menu Button I will close this one.
