Scrollbar invisible, no border on right-click

I use a high contrast theme, because I love yellow on black. With Firefox anymore, the scrollbar is now fully black, so I can't see where I am going. And there is no border on right-click menu (and hovered options there are invisible). This is recent.

Chosen solution

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

I assume this is because you use an inverted High Contrast theme in Windows with a dark background.

I'm not sure whether Firefox works correctly with a dark background theme since this is complicated CSS and Firefox would have to detect the dark background or use some text shadow to work with both dark and light background.

Is that border in the right-click context menu completely missing or only in the border-right and border-bottom where it shows darker for me (top and left are white)?

Do you speak English? If so, you should know that it's fixed.
