Mozilla is set to launch Firefox 132 Stable today. This latest edition introduces numerous significant improvements, such as compatibility with Microsoft PlayReady, enhanced tracking protection, and a range of additional features.
The two versions of Firefox ESR—Firefox ESR 115 for legacy systems and Firefox 128.x—have also been upgraded.
How to Download and Update to Firefox 132.0
Updates are usually intended to install automatically; however, this may not occur immediately, and users will have to restart the browser to finalize the installation.
When the update is available, users can manually initiate it by navigating to Menu > Help > About Firefox.

Key Updates in Firefox 132
Support for Microsoft PlayReady
Windows users of Firefox will now enjoy Microsoft PlayReady support for “certain sites,” allowing 1080p baseline playback as well as 4K Ultra HD for “key streaming partners.”
Currently, Mozilla has not revealed the exact sites or streaming partners that will be included. This feature is being introduced progressively to select platforms.
The integration of PlayReady is anticipated to enhance performance and lessen battery usage while streaming content on compatible sites.
We have contacted Mozilla for additional details and will provide updates as we gather more information.
Note: Users who prefer to disable DRM can do so by modifying the setting media.eme.playready.enabled to False in about:config.
Strict Third-Party Cookie Blocking
With strict mode activated in Firefox’s Enhanced Tracking Protection, third-party cookies will be blocked. This applies to both normal and private browsing modes. Firefox offers three tracking protection options: standard, strict, and custom.
Other Updates and Fixes
- Wide Color Gamut WebGL compatibility has been introduced for both Windows and macOS, resulting in “a richer, more vibrant color palette for videos, games, and images.” This feature is restricted to wider color (P3) profiles in 8-bit format.
- New capabilities for screen and window sharing are now accessible in macOS 15, with intentions to broaden support to macOS 14 in a coming update.
- If Firefox was active before a system reboot, it will automatically reopen on macOS.
Changes for Developers
- WebRender now accommodates hardware-accelerated rendering for most SVG filter primitives.
- Favicons served via HTTP will be blocked if they do not have an upgrade path to HTTPS.
- The “Copy Without Site Tracking” option will be disabled in the context menu if the link does not include tracking parameters.
- The text-emphasis-position property has been revised to support the auto value.
- The JSON parse proposal with source is now executed.
- HTTP/2 Server Push is turned off by default, with the network.http.http2.allow-push preference set to false.

- Certificate Compression support has been added to decrease the size and enhance the speed of TLS handshakes.
