I have a problem with browser zoom in Google Chrome and FireFox. I have one button that is overlapped by another element (my page always have 100% zoom and is very bad for me because a lot of elements are invisible).
I found one solution but it works only before page reload:
driver.execute_script('document.body.style.MozTransform = "scale(0.8)";')
I am looking for a solution in headless browser mode (I use Selenium+Python).
