This is an excellent bookmarklet to have:

``` javascript:(function()%7B let i%2C elements %3D document.querySelectorAll('body *')%3B for (i %3D 0%3B i < elements.length%3B i%2B%2B) %7B if(getComputedStyle(elements%5Bi%5D).position %3D%3D%3D 'fixed' %7C%7C getComputedStyle(elements%5Bi%5D).position %3D%3D%3D 'sticky')%7B elements%5Bi%5D.parentNode.removeChild(elements%5Bi%5D)%3B %7D %7D %7D)() ```

Sometimes, this one is needed to fix scrolling after using the previous one:

``` javascript:var r="html,body{overflow:auto !important;}"; var s=document.createElement("style"); s.type="text/css"; s.appendChild(document.createTextNode(r)); document.body.appendChild(s); void 0; ```
