Hi whipp, could you describe in more detail where you see this change? For example:

• Manage Bookmarks (Library window) (Ctrl+Shift+O as in Organizer)
• Sidebar (Ctrl+B)
• Drop-down from the menu bar or a toolbar

Did any other parts of your browser change to a dark theme that were light-themed before?

Hi, I didn't read down the forum far enough. This is a known issue with some themes. See:

• https://support.mozilla.org/questions/1518730
• https://support.mozilla.org/questions/1518747

For now, could you try switching to the built-in dark theme instead? See: Use themes to change the look of Firefox.

Hello,

The issue should be fixed with the 140.0.1 release. Please update your Firefox and let us know how it goes!
