Apparently found out that replacing 0.0.0.0 with http://0.0.0.0 seems to fix the problem for mozilla.loacation service.

Also, started playing Beneath a Steel Sky. I remember playing it in 2014 on my ubuntu machine. Now it's ported over to Android. If you're into strategic games, I suggest you to give it a try. This game was released in 1994. ^_^

Have a nice day ^_^
