The white background in the autocomplete menu for form autofill seems to be fixed as this menu now matches the password manager autocomplete menu, but there are still issues depending on what Firefox theme you're using.

For example, with a light theme, hovering over an item makes the credit card number, in this case, illegible. There's no such issue if using the Firefox dark theme, but the blue highlight doesn't match the password manager's highlight in either case. I do wonder if the password manager highlight is "incorrect" technically, because it looks like the right click context menu also shows this blue highlight on hover that the form autofill autocomplete menu shows...but that's tangentially related to this bug, so no need to deep dive.

It looks like we need to update the text color in the form autofill autocomplete menu when the High Contrast Black theme is enabled, since that would align this autocomplete menu with the context menu.
