** Note that if a user routinely uses google search to access facebook (or cnn etc), it's highly likely that the main page will already be cached by the browser (or at least many components which this page uses), therefore the "facebook instant effect" which chrome has but Firefox doesn't is not likely to be a meaningful differentiator in practice. | ** Note that if a user routinely uses google search to access facebook (or cnn etc), it's highly likely that the main page will already be cached by the browser (or at least many components which this page uses), therefore the "facebook instant effect" which chrome has but Firefox doesn't is not likely to be a meaningful differentiator in practice. | ||

*** Same issues as Firefox and Chrome, plus when the main display is the laptop, and it has a lower rate than the external display, on both win8/10 -> it uses weird rAF rate (67hz, 64hz) which doesn’t match any monitor. | *** Same issues as Firefox and Chrome, plus when the main display is the laptop, and it has a lower rate than the external display, on both win8/10 -> it uses weird rAF rate (67hz, 64hz) which doesn’t match any monitor. | ||
