0Enable Full Firefox 4 Hardware Acceleration

I’ve found that Fire­fox 4 doesn’t seem to have com­plete hard­ware accel­er­a­tion enabled by default and by using the fol­low­ing tweaks have improved per­form­ance.

Make sure “Use hard­ware accel­er­a­tion when avail­able” is ticked

2. Go to about:config and add or change the following

mozilla.widget.render-mode : 6
gfx.font_rendering.directwrite.enabled : true
webgl.force-enabled : true
