all browser chrome (tab switcher, awesomebar, toolbars) sometimes turn invisible when window is inactive

more options

All the browser chrome including the tab switcher, awesomebar, firefox menu, and toolbars, but not the standard minimize/unmaximize/close buttons, will sometimes turn invisible while the window is inactive.

Clicking back into the window restores them. I have a dual monitor setup, and firefox is maximized on one monitor while I'm working on other applications in the other.

This is an intermittent problem, and has been happening for about a week now, starting from a fresh install of Firefox with a clean profile.
