I need to set up my firefox on a new computer. I have an EXTENSIVE automation program that I have written, thousands of lines of code. I need to have the new firefox look exactly like it does on my old PC. On my old system, the color of the "Bar" directly below the very top "Bar" where "File Edit View History Bookmarks Tools Help" exists has a different color than what I see on my new PC. The old PC shows a grey color, the new PC shows as a bright white. Both Firfoxes are version 112.0.2 (64 bit version) I have looked through the settings and both firefoxes are the same. How do I set this color? Thanks
