This is a very useful theme, for the Firefox 140 update. Up until this point, I have used the Classic Blue by ndnenigmaI. The update has jacked up the text color in the "Show Sidebar" menu (the old type, not the modern one), so I had find another decent blue theme that can make the text legible.

Just what I wanted! Simple solid colors. Just the right background brightness on drop-down lists

Very Nice! Clean and Simple.

Will it better with darker blue and lighter grey ?

깔끔하고 시원합니다. 좋아요

Best one !
