how do i change the black close tab?
The top right corner is black. This should be the maximize/minimize/close tabs, but when I started up the computer today, they show up as a black bar. How do I remedy this?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window

You can also try a different Windows theme.
