Firefox 102: new ESR base and improved security


Firefox 102 and Firefox 102 ESR will be released later today. The new version of Mozilla’s Firefox web browser improves security, picture-in-picture mode, and forms the new foundation for the Extended Support Release channel.

All Firefox development channels receive updates on the same day. Firefox Beta and Firefox Developer editions are moving to version 103 and Firefox Nightly is moving to version 104. Firefox for Android is following the stable channel release, which means it is also moving to version 102.

Summary

  • Firefox 102 ESR is the new base. Firefox 91.x ESR will remain available for the next two releases before being retired on September 20, 2022.
  • Audio decoding is moved to its own process with stricter sandboxing.
  • Firefox mitigates URL query parameters used for tracking in Strict Tracking Protection mode.

Download and update Firefox 102

Firefox 102 and all other versions released today are delivered via the browser’s automatic update feature on most devices. The update may not be available yet if you are reading this on the day it was released.

Direct downloads are also available, follow the links below to the Mozilla download website, to download the new version of the browser.

New features and improvements in Firefox 102.0

Removing query parameters

Firefox automatically removes parameters from URLs when they can be used to identify and track users. The deletion should not affect the loading of the target address.

Starting with Firefox 102, a blocklist is used to remove known tracking parameters from top-level URLs.

The feature is enabled in the browser’s private browsing mode and when Firefox’s Enhanced Tracking Protection feature is set to strict.

Follow these steps to enable Strict Tracking Protection:

  1. Load about:preferences#privacy in the Firefox address bar.
  2. Switch Enhanced Tracking Protection from Standard to Strict.

Hide download panel

Firefox displays the download panel each time a new download starts. Some may not like it, and these users can now disable the automatic opening of the download panel.

To do this, right-click the download icon and select “Show panel when download starts” to toggle the feature. If you don’t see a checkmark in front of it, Firefox won’t show the download panel.

Other Changes

  • Audio decoding now happens in its own process, which improves security through stricter sandboxing.
  • Picture in Picture mode supports subtitles and captions on HBO Max, Funimation, Dailymotion, Tubi, Disney+ Hotstar and SonyLIV.
  • Pressing Enter while using a screen reader on Windows no longer activates the wrong element and/or another window.

Developer

  • The media update feature is now enabled by default.
  • The Window.sidebar property is controlled by a preference, as it will be removed in a future release.
  • The IDBMutableFile, IDBFileHandle, IDBFileRequest interfaces and the IDBDatabase.createMutableFile() method have been disabled by default for removal in a future release.
  • Transform flows are supported by Firefox.
  • Readable byte streams are supported.
  • Add-on developers can use the scripting API, “which provides functionality to run scripts, insert and remove CSS, and manage content script registration,” in Manifest V2 Extensions.
  • Manifest V3 extensions must specify the wasm-unsafe-eval to use WebAssembly. Firefox supports Content-Security-Policy integration with WebAssembly.
  • The nonPersistentCookie option of the privacy.websites cookieConfig property is deprecated.

Company changes

Two new policies added:

  • Use the system print dialog instructs Firefox to use the system’s print dialog. This has the same effect as setting the print.prefer_system_dialog preference to true.
  • ExemptDomainFileTypePairsFromFileTypeDownloadWarnings defines file types for which warnings are suppressed when downloaded.

Mozilla fixed an issue that caused a bug in the policies for protection against deceptive content and dangerous software. Locking policies did not disable the about:preferences UI.

Known issues

none listed.
