Core Apps » Orfox Private Browser

I think this is happening because OrFox has been released with StrictMode on. I'm seeing errors like the following for download of some but not all file types:

Confirmed the version of Orfox in google play was shipped with StrictMode on:

./AppConstants.smali:.field public static final MOZ_UPDATE_CHANNEL:Ljava/lang/String; = "default"

results in enableStrictMode getting called here:

GeckoApp.java

// Enable Android Strict Mode for developers' local builds (the "default" channel).
        if ("default".equals(AppConstants.MOZ_UPDATE_CHANNEL)) {
            enableStrictMode();
        }

Can you rerun the downloads with logcat turned on and post the log here? To confirm this is the same error your getting or not.

In any case the next build should set --enable-update-channel to something other then "default".
