Why do number spinners display without a top border and drop downs ignore the css styling?

I have a simple number spinner and the top border is missing from the control.

When you view the options in a drop down the border to the options is a very harsh black on the bottom and right edges.

We are using bootstrap and firefox doesn't seem to like it at all.

Is there a css setting that can change this as none of the usual border-color/width/style options appear to have any effect at all?

Start Firefox in Safe Mode to check if one of the extensions (Firefox menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox menu button/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
