Mozilla is poised to roll out Firefox 132 Stable today. This new version brings several important enhancements, including support for Microsoft PlayReady, improved tracking protection, and a variety of other features.

The two editions of Firefox ESR—Firefox ESR 115 for older systems and Firefox 128.x—have also been updated.

How to Download and Update to Firefox 132.0

Updates are generally designed to install automatically; however, this may not happen right away, and users will need to restart the browser to complete the installation.

When the update becomes available, users can manually install it by going to Menu > Help > About Firefox.

The latest version of Firefox can also be obtained through the links below:

  • Download Firefox Stable
  • Download Firefox Beta
  • Download Nightly
  • Download Firefox ESR
  • Download Firefox for Android on Google Play

Key Updates in Firefox 132

Support for Microsoft PlayReady

Windows users of Firefox will now benefit from Microsoft PlayReady support for “select sites,” enabling 1080p baseline playback as well as 4K Ultra HD for “key streaming partners.”

At this time, Mozilla has not disclosed the specific sites or streaming partners that will be included. This feature is being rolled out gradually to select platforms.

The implementation of PlayReady is expected to improve performance and reduce battery drain while streaming content on compatible websites.

We have reached out to Mozilla for more information and will update as we learn more.

Note: Users who wish to turn off DRM can do so by adjusting the setting media.eme.playready.enabled to False in about:config.

Strict Third-Party Cookie Blocking

With the strict mode enabled in Firefox’s Enhanced Tracking Protection, third-party cookies will be blocked. This applies to both standard and private browsing modes. Firefox offers three tracking protection scenarios: standard, strict, and custom.

Other Updates and Fixes

  • Wide Color Gamut WebGL support has been introduced for both Windows and macOS, resulting in “a richer, more vibrant color palette for videos, games, and images.” This feature is limited to wider color (P3) profiles in 8-bit format.
  • New functionality for screen and window sharing is now available in macOS 15, with plans to extend support to macOS 14 in an upcoming update.
  • Firefox will automatically reopen on macOS if it was previously running before a system restart.

Changes for Developers

  • WebRender now supports hardware-accelerated rendering for the majority of SVG filter primitives.
  • Favicons served over HTTP will be blocked if they lack an upgrade path to HTTPS.
  • The “Copy Without Site Tracking” feature will be disabled in the context menu if the link does not contain tracking parameters.
  • The text-emphasis-position property has been updated to support the auto value.
  • The JSON parse proposal with source is now implemented.
  • HTTP/2 Server Push is disabled by default, with the network.http.http2.allow-push preference set to false.
  • A post-quantum key exchange mechanism for TLS 1.3 has been introduced.
  • Certificate Compression support has been implemented to reduce the size and enhance the speed of TLS handshakes.

Enterprise Updates

More details will be provided shortly.
