Background

In Firefoxâ€™s fullscreen mode, toolbars and the tab strip are hidden at the top of the screen and only shown on mouseover. To draw attention to this, they are shown sliding upwards and off-screen when fullscreen mode is toggled on. This preference determines the behavior of that animation.

Possible values and their effects

[edit]

0

Do not animate the collapsing toolbars/tabstrip.

[edit]

1

Only animate the first collapse; subsequent collapses are instant. (Default)

[edit]

2

Animate every collapse.

[edit]

Caveats

This preference is defaulted to 1 for performance reasons â€” the animation can be a little choppy, and some prefer the immediate collapse.
browser.fullscreen.autohide must be true for this preference to have an effect.
