v1.2: Bright mode is back!
Firefox 96 harmonizes more parts of Firefox with your toolbar theme. When the text color on your "toolbar text" is light/white, it triggers Firefox to use a dark background on menus, the sidebar, the Library window, and various built-in pages. Firefox also signals sites that you have a dark theme preference.
Due to this limitation and since this should be a brightmode theme, I had to change the toolbar text to a dark blue color and increase the brightness of the toolbar background, so it remains readable.

Get v1.0 if you like the dark menus more.
