With the recent launch of Firefox 143, Mozilla has promoted the upcoming version, Firefox 144, to the beta channel for public testing. This new release focuses on enhancing the security of saved logins in the Firefox Password Manager. The update will transition from the outdated 3DES-CBC encryption method to the more modern AES-256-CBC, thereby strengthening the local encryption of logins stored on disk.
Mozilla notes that this change is limited to local encryption; logins synced through Firefox Sync remain end-to-end encrypted with the already robust AES-256-GCM.
In addition to encryption improvements, Firefox 144 introduces a more user-friendly Picture-in-Picture feature, allowing users to close the PiP window without interrupting the video by using Shift + Click on the close button or Shift + Esc to exit. For Firefox on Android, the version will also see the removal of the setting that allowed screenshots during private browsing sessions.
Web developers will benefit from various new features in Firefox 144. Updates include support for the Element.moveBefore API, enhancements to the PerformanceEventTiming.interactionId, and added support for the View Transition API. Developers can also crop and downscale video capture using the new resizeMode constraint in getUserMedia.
Furthermore, the update includes support for the WebGPU API’s GPUDevice.importExternalTexture on Windows systems and introduces an upsert proposal for Map and WeakMap objects. Other technical enhancements include worker transfer support for RTCDataChannel, and updates to methods in the ScreenOrientation interface for Windows tablets and Android devices.
Firefox Labs receives attention as well, debuting a new feature titled "Lists and timer on Firefox Home," promoting productivity by helping users manage to-do lists and set timers for focus.
Mozilla plans to release Firefox 144 officially on October 14, 2025, alongside other updates, including Firefox 140.4 and 115.29.0 ESR. Meanwhile, users can download the latest Firefox 144 beta from the official website, keeping in mind that it should not be used for production work.
