Foxfooding Firefox for Android and iOS

September 20 - October 08, 2021

Help us test Firefox on mobile! 

Mozilla has been working on improving Firefox for Android and iOS to help people get back to what they care about. 

With your help we want to uncover any problems with the new design and also discover opportunities to improve the design!

We will update areas for testing once in a while, so you will have new things to explore.

Foxfooding is important for getting wider feedback for new features! It also gives you the opportunity to check out our newest features before they are released to the public.

Step 1: Install the right app

  1. Install or update Firefox Nightly via the Google Play store
  2. Open the 3 dot menu in the lower-right corner of the page
  3. Tap the “Settings” button and toggle the “Set as default browser” option ON.
iOS for iPhone and iPad:
  1. Install or update Firefox Beta via Testflight (open the link and follow the on-screen instructions)
  2. Tap the “Start Testing” button from the Firefox section.
  3. When Firefox Beta is displayed in Testflight, tap the “Accept” button and then the “Start Testing” button.
  4. Once the browser is launched, tap the bottom-right menu button and tap the “Settings” option.
  5. Tap the “Set as Default Browser” option.

Once you have installed or updated the app, please follow the instructions below – the screenshots are from Android but the implementation on iOS is comparable.

Step 2: start testing!

If you need help or want to chat with other participants, you can join the #foxfooding channel in Matrix. If you find any bugs, please submit them here.

Step 3: Give Feedback

To give feedback, use Firefox as you’d normally do for at least 1 week,  and keep an eye on how useful you find the things that you see on home/new tab.
  • Which sections do you use frequently?
  • Which sections do you never use?
  • Do the sections have relevant content?
  • Do you wish there was something more showing in any section?
  • Is there any sensitive information that you wish didn’t show up on the homepage?
After 1 week of testing, we will send a survey link to all subscribers to the campaign. Make sure to subscribe to be able to give feedback!
