Firefox 149 to Roll Out March 24 With Free Built-In VPN

Mozilla is positioning the browser-only proxy as a trust-first option, trading system-wide coverage for simplicity and a generous 50GB monthly allowance.

Overview

  • The free VPN arrives in Firefox 149 on March 24 with 50GB of monthly data at launch in the United States, United Kingdom, Germany, and France.
  • Protection is limited to Firefox traffic via a Mozilla-managed proxy that auto-connects to the nearest server, so it is not designed for geo-unblocking or full-device coverage.
  • Mozilla says it will not log the sites users visit and that account-linked data is deleted after three months, distinguishing the feature from many free VPNs.
  • The browser feature is separate from the paid Mozilla VPN, which provides system-wide protection, and activation of the free tier requires a Mozilla account.
  • Firefox 149 also adds Split View and Tab Notes, plus an opt-in Smart Window AI assistant, with Mozilla signaling further controls and safeguards after launch.
