I cleaned up and improved this a little. Now it hides the fixed elements, unless their computed top is at 0px. Also makes the body to scroll automatically, as many sites set their body to fixed before the fixed popup is gone:

``` javascript:(function () { var i, elements = document.querySelectorAll('body *'); var style;

    document.body.style.overflow-y = 'auto'
    for (i = 0; i < elements.length; i++) {
        style = getComputedStyle(elements[i]);
        if (style.position === 'fixed' && style.top !== "0px") {
            elements[i].style.display = 'none';
        }
    }

})() ```
