​Hi Terry, don't worry—you haven't lost anything! "Firefox" and "Google" are just different tools to get to the internet, and your apps and files are still safe on your phone. ​Here is the easiest way to switch back to your preferred browser: ​1. How to switch back to the Google app ​If you prefer using the Google app (the "G" icon), you don't need to delete Firefox. Simply: ​Close Firefox and look for the Google app or the Chrome app (the red, yellow, green, and blue circle icon) on your phone's home screen. ​Tap it, and you will be back to the interface you are familiar with. ​2. How to set Google/Chrome as your "Default" ​If you want your phone to stop opening Firefox automatically: ​Open your phone’s Settings (the gear icon). ​Go to Apps (or Apps & notifications). ​Tap Default apps (you might need to tap "Advanced" or the three dots to find this). ​Tap Browser app. ​Select Chrome (or Google) from the list. Now, your phone will use that for all links. ​3. Why did this happen? ​Firefox and Mozilla are the same thing—Mozilla is the organization that makes the Firefox browser. It likely became your default app if you accidentally tapped "Always" when opening a link, but changing it back is very easy using the steps above. ​Note: You do not need to "cancel" or delete Firefox. Leaving it installed won't hurt your phone, but if you truly want it gone, you can long-press the Firefox icon on your home screen and select Uninstall.
