  "account": "Mozilla has released Firefox 155 and Thunderbird 155, marking the start of a new fortnightly release cycle. The updates come with several new features, particularly in the realm of AI, such as a Smart Window, smarter tab-group naming, and a counter for blocked trackers in the address bar. Other improvements include faster page loading, better support for game controllers, and the ability to display PDFs larger to fit on a printed page. Firefox users can disable these AI features using a kill switch. Thunderbird 155 introduces a QR code export feature for syncing with Android devices, along with several bug fixes and security enhancements. Users can also choose their default address book and customize OAuth authorization settings. For those seeking a more stable option, Mozilla continues to offer the Extended Support Release (ESR) versions of Firefox and Thunderbird.",
