Another way to reach new users. The only other major browser I can see on there is Opera. Therefore, having Firefox as an option could potentially increase user numbers by quite a lot. Amazon Fire tablets are very popular, and at the moment the average user essentially has the option of the built in browser, or Opera.
Many years ago, Mozilla withdrew Firefox from the Amazon AppStore after Amazon refused to stop modifying Firefox with some code that Mozilla found offensive (presumably for privacy/tracking reasons). Perhaps it is time to try again?
How do I install on fire tablet. When I go to the Amazon app it says unavailable?
