In about.config i set javascript.enabled false for most browsing, unless i really need to do otherwise (e.g. ecommerce). If i close the app (menu quit), and restart it, javacript.enabled is reset true. This behaviour is not replicated for other settings i may make, e.g. dom.storage.enabled, or permissions.default.image. Being Android i have no root so no possibility of creating a user.js to override Firefox ignoring my settings. This seems to be a bug. Version is Android Nightly version 121.0a1, 2023-11-05.
