Hi,

Please:

1. tap the three bar icon at the top right of your screen while in firefox
2. tap on settings
3. tap on customize
4. tap on search
5. now tap on Google
6. then press set as default.

And if you mean that the default search engine keeps reverting to yahoo, follow the steps above, except instead of tapping on Google, tap on Yahoo, then tap remove to remove Yahoo all together.

I hope this helps!

I prefer Google and the yahoo safe search keeps resetting...it's anoying. Thanks

Thanks, this was easy but it takes a while to learn new phones.
