Chosen solution

Your user agent shows that you run Firefox in compatibility mode for Windows 98 (NT 4.10).

  • User Agent: Mozilla/5.0 (Windows NT 4.10; rv:43.0) Gecko/20100101 Firefox/43.0

Check that you do not run Firefox in compatibility mode. You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
