- What is the current behavior? When you select a white text on a red background you can't see it actually getting selected, because the selection is the same color.

- If the current behavior is a bug, please provide the steps to reproduce.

• Open any page that has a red background with that on it, example: Author page
• Try to select Author text, title, paragraph anything.

Or try to select something in a footer.

- What is the expected behavior? You would expect to see the selection, because at first I thought it was a z-index problem but it turned out I selected the text.

- Please mention your operating system version and the version of your browser FF 52.0.1
