I’ve haven’t used it before just now but the Android version of Firefox has an extension called “MobiDevTools” on their extension store. It has various web developer tools, including a developer console. For some reason it doesn’t seem to open when I’m on the extension store but it works just fine with every other website I tried.
On older android devices, I immediately enable developer mode so I can enable “force GPU rendering”. You’d be surprised how much of a difference it can make when games are unoptimized and don’t use the GPU to render anything. For some reason, this setting was removed from newer versions of android.
