A few days ago, my Firefox browser stopped clearing browsing data, cookies, history, cache. I am using a custom-built desktop computer with Windows 10 Home, Firefox v. 143.0.4. What is the setting I need to change so this will start clearing data again? The "Clear data and cookies" no longer works, and my search has brought up no other options that I have found. I need simple instructions, please.
