What's new in 1.12b

Firefox 138.0.1
GitHub Release
GitHub Run

A nice update that brings some cool new features and fixes!

We are also excited to announce that we've joined floss.social!

In response to recent privacy concerns, we've significantly strengthened Zen's privacy measures. Previously, we only disabled telemetry, but some minimal pings were still being sent. Now, Firefox telemetry has been completely stripped out from the core.

Additionally, onboarding pages and initial Essentials favicons are now locally bundled and our website no longer relies on any external services, CDNs, nor Cloudflare services. Initial Essentials selected on startup will only be loaded when the tab is clicked on, so connections won't be established until you explicitly enter the tab. We also changed our onboarding Essentials options to more privacy and productivity focused sites.

Only critical security updates and other non-telemetry-related services remain. As a result, the number of external connections has dropped from 82 to around 20-10 — factoring in that Zen's site is loaded twice (for the welcome page and privacy policy).

Psst. With the release of Firefox 138, folders are just around the corner!
