Is there a way to adjust a pages CSS?

[mrmadman]

I want to block an element from loading.

Its a pop that appears (on facebook) when you hover over someones name or profile picture. When using full mouse movement and emulation it can sometimes appear over the element i am trying to click and then zenno clicks on the popup instead.

You must capture html code into a variable, search for the element in html code and replace that value, sometimes its something like "display: block" or "aria-hidden = false", you must set "display: none" or "aria-hidden=true".
