Mozilla usually sends a ping to your browser and that's how they know you are using firefox and that's how Mozilla counts the reducing number of users who are using FF, so I was wondering if this survey includes forks of FF.
PS: If you turn off telemetry completely, you won't be counted in surveys, most Mozilla forks are more private by default than FF itself. So, I was wondering if more people were using forks and abandoning FF for privacy reasons. Thus reducing the count. That makes sense?
