The Smoothing control (None/Grayscale/Subpixel) and the Subpixel Order control (RGB/BGR/VRGB/VBGR) takes effect after a restart of Firefox (though in other applications it takes effect immediately). The Hinting control (None/Slight/Medium/Full) does not take effect in Firefox.
AFAIK there’s no GNOME control for the LCD filter.
