Preliminary investigation shows that this event gets fired at the right time.

Sample flow:

• User has Firefox as default browser
• User opens iOS Mail app
• User opens an email with a link and taps on it
• Link opens in Firefox

• An event get sent to glean app_opened_as_default_browser

  enum App { /// Recorded when a preference is changed and includes the /// preference that changed as well as the value changed to /// recorded in the extra keys. static let openedAsDefaultBrowser = CounterMetricType( category: "app", name: "opened_as_default_browser", sendInPings: ["metrics"], lifetime: .ping, disabled: false ) }

After more investigation I think I figured out whats going on. In the original query the regex was incorrect and it wasn't including version 30.0 of our iOS Firefox app in the result and hence we got incorrect values from our query.

I have forked the original query and made changes so that it has proper regex and that will also include v30 of iOS Firefox App when it runs Set as Default Browser query. I have also added comments in the query as well.
