Alt key with Linux Nightly brings up the menu bar

As part of Australis (I assume) pressing and releasing the alt key now brings up the full menu bar on Linux. This is contrary to the expected user experience of a modifier key. A modifier should do NOTHING when pressed and released by itself, they exist to modify other key presses. The new behavior is REALLY annoying, and I wonder if anyone knows how to turn it off. The usual suspects like "menu" and "alt" in about:config didn't come up with anything useful.

You might want to ask about disabling that functionality in an Australis Builds thread over at MozillaZine.

Most of the users who test the pre-release builds, such as Nightly and Aurora, use the MozillaZine Builds forum to share information.

You can set the ui.key.menuAccessKeyFocuses pref to false on the about:config page.
This requires to close and restart Firefox.

IIRC this has been a long standing function of the Alt key. It did something similar in Windows XP after the Firefox Button was introduced.

The alt key has never opened the window for me (elementary os), but F10 does.

Ah..... ui.key.menuAccessKeyFocuses was set to false be default for me.
