Also, a new result menu has been added making it easier to remove history results and dismiss sponsored Firefox Suggest entries.
• Private windows now protect users even better by blocking third-party cookies and storage of content trackers.

• Users on macOS can now access the Services sub-menu directly from Firefox context menus.
• On Windows, the elastic overscroll effect has been enabled by default. When two-finger scrolling on the touchpad or scrolling on the touchscreen, you will now see a bouncing animation when scrolling past the edge of a scroll container.

Fixed

Various security fixes.

Developer

Developer Information

There have been numerous improvements to the Debugger's "Search in files" feature (also known as "Project search"):

• The panel has been moved to a regular side panel, which allows you to keep the results list visible while opening scripts in the editor;
• Results from minified and pretty-printed tabs, as well as matches from the node_modules folder, are displayed;
• Results from ignored files are hidden; and
• Glob patterns and search modifiers are also supported, making it possible to execute case-sensitive or regex searches on specific parts of your project. Additional features include support for pretty printing inline scripts in HTML files and column breakpoints in pretty printed sources.

It is now possible to override a JavaScript file in the debugger. In the Debugger, under the Sources tree, you can use the "Add script override" context menu entry. This action will download the file onto your machine, allowing you to edit it. After reloading the page, the local file will be loaded instead of the original script (indicated by a purple icon when a file is overridden).

Web Platform

• Module scripts can now import other ES module scripts on worklets.
• Firefox 113 includes new CSS functionality, including improved support for the color (level 4) specification (such as the lab(), lch(), oklab(), oklch(), and color() functions) and the scripting media query.
• Firefox 113 adds support for a number of WebRTC features for improved interoperability: RTCMediaSourceStats, RTCPeerConnectionState, RTCPeerConnectionStats ("peer-connection" RTCStatsType), RTCRtpSender.setStreams(), and RTCSctpTransport.
• The forced-color-adjust property is now supported, allowing authors to opt an element out of color changes in Forced Color Mode for improved readability where the automatically-picked contrasting colors are not ideal.

Erneut verursacht die Software von Avast und AVG Probleme für Firefox-Nutzer. Dieses Mal in Form häufiger Firefox-Abstürze unter Windows. Mozilla hat Firefox 105.0.3 veröffentlicht, um das Problem zu umgehen.

Community version of the popular extension "I don't care about cookies"

Version 105.0, first offered to Release channel users on September 20, 2022

New

• Added an option to print only the current page from the print preview dialog.
• Firefox now supports partitioned service workers in third-party contexts. You can register service workers in a third-party iframe and it will be partitioned under the top-level domain.
• Swipe to navigate (two fingers on a touchpad swiped left or right to perform history back or forward) on Windows is now enabled.
• Firefox is now compliant with the User Timing L3 specification, which adds additional optional arguments to the performance.mark and performance.measure methods to provide custom start times, end times, duration, and attached details.
• Searching in large lists for individual items is now 2x faster. This performance enhancement replaces array.includes and array.indexOf with an optimized SIMD version.

Fixed

• Stability on Windows is significantly improved as Firefox handles low-memory situations much better.
• Touchpad scrolling on macOS was made more accessible by reducing unintended diagonal scrolling opposite of the intended scroll axis.
• Firefox is less likely to run out of memory on Linux and performs more efficiently for the rest of the system when memory runs low.
• Various security fixes.

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 105 Release Notes.

Web Platform

Support for the Offscreen Canvas DOM API with full context and font support. The OffscreenCanvas API provides a canvas that can be rendered off-screen in both Window and Web Worker contexts.

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.

Today’s release of Total Cookie Protection is the result of experimentation and feature testing, first in ETP Strict Mode and Private Browsing windows, then in Firefox Focus earlier this year. We’re now making it a default feature for all Firefox desktop users worldwide.

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.

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.

A website asking me to "disable ad-blocker" has the balls to tell me I should turn off Firefox Tracking Protection. That's like saying "yeah, we absolutely want to track you across websites, would you do us a favor and let us do it? Please :)"
