I'm running a Drupal website (www.radiantfreedom.com) and since updating to Firefox 60.0.2 I noticed the dynamic menu (to reveal sub menus on hover) is no longer working. I'm stuck with default Drupal behaviour and no changing of modules to use different modules that add this same feature would resolve the problem. Upon inspecting my site's CSS, I discovered the CSS code to implement the dynamic hover effect on menus is in place but not executing in Firefox. I get the same issue in the latest version of Chrome. I have changed nothing in my website's code that would affect this since the error started, the only changes since then are updates to my browser. I'd like to access a legacy version of firefox, starting at v60.0.1 or earlier to test if this issue is coming from Firefox or Drupal. It should NOT be coming from Drupal though, as I have made no changes to my site at all, so I really need to test if this issue is coming from the browsers. I've spend hours debugging and trying to fix this issue and I'm getting nowhere.
