I would recommend downloading Firefox uploaded by the official developers in the App store of your mobile instead of downloading it from a third-party website to avoid your details/accounts getting compromised. It is not very difficult to edit a software and integrate a Keylogger into it and then upload it to a third-party server and provide the link to people to download and use it. Such practices usually steal information from people costing them money or accounts in general.

I'm not blaming OP since I know what he did here is only to help others and he may have no relation with the link he provided, but I just wanted to let the ones who don't know about such things be careful when they are following something like this any time, whether in mobile or computers.

@OP, I've given you a Merit for at least doing some work taking snaps and all which consumes some time and that is always a good thing if someone spends time for only helping others.
