Since there is a META in place and the issue still reproduces, I will close this as a duplicate of the META bug.

Firefox changes scrollbar colour based on html/body background colour, which is a product choice and doesn't affect usability of the site, so this is not actionable for now. If there are reports coming from users affected in any way, we can reconsider the decision in the future.
