title: :hover state is still active after going back in browser by using browser back-button
body: <p>I hover over an link in my nav and it changed its color.</p>
  
  <p>I have a strange problem in Firefox and Safari: when i go back in the browser(by clicking the back-button with the mouse) after hovering a link the color of the link does not change to its original state. It has the hover-state.</p>
  
  <p>Only after the mouse reenters the site the color is changed back to black.
  What can i do to change the color of the link back to black immediately on pageload. Why the hover-state seems to be active on pageload?</p>
  
  <p>This happens when I hover a link an afterwords I go directly with the mouse to the back button of the browser. </p>
  
  <p>Thanks a lot!</p>
