SafeSearch keeps turning on automatically — how do I disable it?

Hi, Every time I search using Firefox (especially through the address bar or default search), SafeSearch is automatically enabled — even though I never turned it on and don’t want it. I’ve tried checking Firefox settings, search engine settings, and even my browser profile, but nothing seems to work. I’m not sure if this is a browser setting, an issue with my account, or something being forced externally (like by Google or Bing). Can someone tell me: Why SafeSearch is always on? How can I turn it off permanently? Is this tied to Firefox itself or to the search engine provider? Using latest Firefox version on Android 15.
