A new stable release of Mozilla’s web browser, Firefox 37, was released today at the end of March.
According to the release note, Firefox 37 brings a heartbeat user rating system to get user feedback about Firefox. Every day a random subset of users are offered a rating widget. After rating Firefox, an ENGAGEMENT page may open in a background tab.
