Done
Look for the default browser box
Set Firefox as your default browser app? Ours listed Chrome (Current default), DuckDuckGo and Firefox.

In the phone's Settings, tap Apps, then Default apps, then Browser app. Google gives the same route. This shot is from after we set Chrome back, so it says Chrome.

About this guide

Firefox asks to become the default browser the first time you open it. On our Pixel it said No permissions needed.

The screenshots are from our Google Pixel 10a with Android 17 and Firefox 158.0.2 from the Play Store, taken on 25 October 2026. We set Firefox as the default for the screenshots, then set Chrome back.
