Thank you for trying Firefox for iOS! Currently, Apple does not let you change the default browser on iPad, iPhone and iPod touch devices. You can, however, send pages from Safari to Firefox by tapping the share icon (the box with an arrow coming out of it) and choosing Firefox as the destination. If Firefox is not listed in the options, tap the More button (three dots) and tap the switch next to Firefox to enable it. If you would like to see this change in the future, please leave feedback for Apple on their site: [http://www.apple.com/feedback/]. I hope that helps. Let us know if there's anything else we can do.
