I'm also using Ubuntu 18.04 but using the vanilla GNOME session (that uses Wayland) with the dark Adwaita theme selected. Could you please test with that to see if you get the same result?

Now I see all the input boxes and buttons filled with grey colour. This happened even with Firefox 2, but I solved that problem with a quick guide under the comment "firefox fix" by Proton at the bottom of this page: http://www.gnome- look.org/content/show.php/Grey+Neu?content=60824 In Firefox 3 I can't correct this problem.
