Mozilla Firefox 102 was released today with a new privacy feature that strips parameters from URLs that are used to track you around the web.

Numerous companies, including Facebook, Marketo, Olytics, and HubSpot, utilize custom URL query parameters to track clicks on links.

With the release of Firefox 102, Mozilla has added the new 'Query Parameter Stripping' feature that automatically strips various query parameters used for tracking from URLs when you open them, whether that be by clicking on a link or simply pasting the URL into the address bar.

Version 100.0, first offered to Release channel users on May 3, 2022

Thank you to everyone who got us here: To every employee past and present who played a role in delivering Firefox—thank you for your grit and hard work. To every contributor who championed open source, thank you for turning a browser into a movement!

Finally, thanks to every user of Firefox—thank you most of all. We didn’t get here—17 years and 100 versions later—without your support. Your choice to use Firefox contributes directly to a better web, keeping it open and accessible to all. It is with a profound sense of gratitude and appreciation that we will continue fighting for this global public resource, putting people over profits.

New

• We now support captions/subtitles display on YouTube, Prime Video, and Netflix videos you watch in Picture-in-Picture. Just turn on the subtitles on the in-page video player, and they will appear in PiP.
• Picture-in-Picture now also supports video captions on websites that use WebVTT (Web Video Text Track) format, like Coursera.org, Canadian Broadcasting Corporation, and many more.
• On the first run after install, Firefox detects when its language does not match the operating system language and offers the user a choice between the two languages.
• Firefox spell checking now checks spelling in multiple languages. To enable additional languages, select them in the text field’s context menu.
• HDR video is now supported in Firefox on Mac—starting with YouTube! Firefox users on macOS 11+ (with HDR-compatible screens) can enjoy higher-fidelity video content. No need to manually flip any preferences to turn HDR video support on—just make sure battery preferences are NOT set to “optimize video streaming while on battery”.
• Hardware accelerated AV1 video decoding is enabled on Windows with supported GPUs (Intel Gen 11+, AMD RDNA 2 Excluding Navi 24, GeForce 30). Installing the AV1 Video Extension from the Microsoft Store may also be required.
• Video overlay is enabled on Windows for Intel GPUs, reducing power usage during video playback.
• Improved fairness between painting and handling other events. This noticeably improves the performance of the volume slider on Twitch.
• Scrollbars on Linux and Windows 11 won't take space by default. On Linux, users can change this in Settings. On Windows, Firefox follows the system setting (System Settings > Accessibility > Visual Effects > Always show scrollbars).
• Firefox now supports credit card autofill and capture in the United Kingdom.
• Firefox now ignores less restricted referrer policies—including unsafe-url, no-referrer-when-downgrade, and origin-when-cross-origin—for cross-site subresource/iframe requests to prevent privacy leaks from the referrer.

Fixed

• Users can now choose preferred color schemes for websites. Theme authors can now make better decisions about which color scheme Firefox uses for menus. Web content appearance can now be changed in Settings.
• Beginning in this release, the Firefox installer for Windows is signed with a SHA-256 digest, rather than SHA-1. Update KB4474419 is required for successful installation on a computer running Microsoft Windows 7. For more details about this update, visit the Microsoft Technical Support website.
• In macOS 11+ we now only rasterize the fonts once per window. This means that opening a new tab is fast, and switching tabs in the same window is also fast. (There's still work to do to share fonts across windows, or to reduce the time it takes to initialize these fonts.)
• The performance of deeply-nested display: grid elements is greatly improved.
• Support for profiling multiple java threads has been added.
• Soft-reloading a web page will no longer cause revalidation for all resources.
• Non-vsync tasks are given more time to run, which improves behavior on Google docs and Twitch.
• Geckoview APIs have been added to control the start/stop time of capturing a profile.
• Various security fixes.

Changed

• Firefox has a new focus indicator for links which replaces the old dotted outline with a solid blue outline. This change unifies the focus indicators across form fields and links, which makes it easier to identify the focused link, especially for users with low vision.
• New users can now set Firefox as the default PDF handler when setting Firefox as their default browser.
• Some websites might not work correctly in Firefox version 100 due to Firefox's new three-digit number. You can read about it in our blog post here!

See the Mozilla Support article Difficulties opening or using a website in Firefox 100 for possible workarounds you can use. There, you will also find instructions for reporting a broken website so that Mozilla can help fix the problem.

Enterprise

Various bug fixes and new policies have been implemented in the latest version of Firefox. You can find more information in the Firefox for Enterprise 100 Release Notes.

Developer Information

Web Platform

• Support for the WritableStream API has landed. WritableStreams provide an interface for writing streaming data to a sink object.
• Additionally, ReadableStream gained support for the “pipeTo” method, which allows you to connect a ReadableStream to a WritableStream. For example, this would allow you to process data retrieved using “fetch” with the WritableStream Sink object.
• Support for WASM Exceptions is now available. This allows C++ exception handling and unwinding/destructing semantics to be expressed in WASM without an additional JavaScript helper code—and at zero cost to code that does not rely on exception semantics.

It's probably well known at this point, but it doesn't hurt to spread the word further. Disabling accessibility services in Firefox (both on desktop and mobile, but specially on mobile) helps A LOT with performance and RAM usage.

Just set accessibility.force_disabled to 1 in about:config and enjoy the up to 20% less RAM usage and 5% less CPU usage (at least in my not so detailed testing on my laptop).

In my case my system went from 7.9GB to 5.2GB with the same tabs and windows open and from 25% to 20% CPU usage while having one of those tabs playing a livestream.

Quoting one of the comments in the Reddit thread I found this out to why this isn't disabled by default:

Accessibility does not start by default, but it starts lazily if another piece of software on your device starts requesting accessibility features from Firefox.

Unfortunately a lot of third-party software likes to do this even though they have nothing to do with assistive technologies.

You can also vote on this bug in Bugzilla to help it get solved faster.
