title: Remove new Firefox autofill color
body: <p>A few days ago my Firefox Developer Edition updated to version 67.0b2 (64 bit). Since then all autofilled input fields have a yellow background, on literally every website.  </p>
  
  <p>How can I get rid of the yellow autofill color? </p>
  
  <p>Changing inset box-shadow color doesn't seem to work like it does in Chrome.  </p>
