Hi Chazmanian, could you describe the steps you're taking and where they are failing? I assume you installed the Uber app. Then when you were registering, Uber generated some kind of message to verify your information (e.g., validate your email address). For example, maybe they sent you a code via text message that you need to enter into the Uber app. Is that what's going on? This forum provides support for Firefox for Android, but if the problem is in the Uber app, we probably can't help with that.
