I’ve observed a consistent issue across several Android devices using Firefox (latest stable version). When trying to launch or interact with certain modded APK-based games—especially those with unpacked resources or modified DEX structures—Firefox either freezes or crashes unexpectedly.

Interestingly, this behavior doesn’t occur on other browsers like Chrome or Samsung Internet. In fact, some third-party websites seem to handle these APKs with stable performance, suggesting it's not an issue with the APKs themselves but possibly how Firefox handles local server callbacks, file-based intents, or memory allocation under WebView.

I’m wondering if this could be tied to Firefox’s stricter security sandboxing, CSP enforcement, or service worker management?

Are there any logs, flags, or debugging routes I can use to isolate the problem further?
