LibreWolf Changelog

What's new in LibreWolf 124.0.1-1

Mar 24, 2024
  • Security fixes.

New in LibreWolf 123.0.1 (Feb 24, 2024)

  • New:
  • We’ve integrated search into Firefox View. You can now search through all of the tabs on each of the section subpages - Recent Browsing, Open Tabs, Recently Closed Tabs, Tabs from other devices, or History.
  • Having any issues with a website on Firefox, yet the site seems to be working as expected on another browser? You can now let us know via the Web Compatibility Reporting Tool! By filing a web compatibility issue, you’re directly helping us detect, target, and fix the most impacted sites to make your browsing experience on Firefox smoother.
  • Fixed:
  • When translating web pages, we are now also translating text in tooltips (i.e. titles) and text displayed in form controls (i.e. placeholder).
  • Various security fixes.
  • Changed:
  • Address bar settings can now be found in the Firefox Settings' Search section.
  • Improved PGO optimizations for macOS ARM64 and Android
  • Off-main-thread canvas on macOS, Linux and Android
  • Enterprise:
  • You can find information about policy updates and enterprise specific bug fixes in the Firefox for Enterprise 123 Release Notes.
  • Developer:
  • The Network Monitor now supports saving a response body to disk through the Save Response As context menu item. This replaces the Save Image context menu item, which only supported saving images.
  • Web Platform:
  • We now implement linearRGB interpolation for SVG gradients, as well as the existing sRGB interpolation. You can choose which to use via the color-interpolation property.
  • Previously, SVG feImage elements that pointed to SVG content required the SVG document to have a root element that had non-percentage width and height values. Such content will now fall back to use the default replaced element values of 300px width and 150px height and the feImage will no longer fail to render.
  • By enabling Preload and Modulepreload support, Early Hints are now fully supported.
  • Audio echo cancellation can now be applied to microphone inputs when the audio output is redirected to another device with setSinkId().
  • Firefox now supports declarative ShadowDOM, providing developers greater flexibility and improved ergonomics when working with ShadowDOMs directly within HTML.

New in LibreWolf 122.0.1-2 (Feb 14, 2024)

  • Fixed:
  • Fixed the Library and Sidebar context menus only displaying Multi-Account Containers icons in the "Open in New Container Tab" menu. (Bug 1876518)
  • Fixed an issue when clicking the Dismiss button in notification pop-ups on Windows causing a webpage in a new tab. (Bug 1848801)
  • Fixed the yaru-remix system theme not applying correctly on Linux. (Bug 1877002)
  • Fixed adding an extra new line to a rule in the Developer Tools' Inspector when copying it to the clipboard. (Bug 1876220)
  • Rolled back a keyboard behavior change made to the Developer Tools' Rules view when validating a property name or input with the Enter key.
  • This moves the focus to the next input, as was the behavior in Firefox 121. (Bug 1877457)

New in LibreWolf 122.0-1 (Jan 24, 2024)

  • Firefox now displays images and descriptions for search suggestions when provided by the search engine.
  • The translations feature received an improvement in the quality of translated webpages. The results should be much more stable. This fixes issues where the content of a page could disappear when translated, or interactive widgets could break.
  • Firefox now supports creating and using passkeys stored in the iCloud Keychain on macOS.
  • MDN Web Docs article suggestions from Firefox Suggest will be available in the address bar for users searching for web development-related information.
  • The line breaking rules of Web content now match the Unicode Standard. This improves Web Browser compatibility for line breaking. An additional improvement for East Asian and South East Asian end users, Firefox now supports proper language-aware word selection when double-clicking on text for languages including Chinese, Japanese, Burmese, Lao, Khmer, and Thai.
  • Firefox now ships with a new .deb package for Linux users on Ubuntu, Debian, and Linux Mint.
  • Various security fixes.

New in LibreWolf 121.0-1 (Dec 25, 2023)

  • New:
  • Firefox now prompts Windows users to install the Microsoft AV1 Video Extension to enable hardware decoding support for the AV1 video codec from about:support if not already installed.
  • Firefox now supports Voice Control commands on macOS systems.
  • On Linux, Firefox now defaults to the Wayland compositor when available instead of XWayland. This brings support for touchpad & touchscreen gestures, swipe-to-nav, per-monitor DPI settings, better graphics performance, and more.
  • Note that due to Wayland protocol limitations, Picture-in-Picture windows require an extra user interaction (generally right-click on the window) or a shell / desktop-environment tweak. See bug 1621261 for related discussion and tracking, this post for a KDE configuration, and this extension for GNOME. It is also a known issue that windows are not correctly placed when restoring a previous session on launch.
  • Firefox can now force links to always be underlined. This option can be enabled in the Browsing section of the Firefox Settings menu.
  • Fixed:
  • Various security fixes.
  • Ubuntu Firefox Snap builds did not default to Wayland compositing on some systems as expected when Firefox 121 was first released. This is now fixed and updated builds can be installed with the Ubuntu Software Updater.
  • Developer:
  • Developer Information:
  • The Firefox Debugger now includes a new feature: an option to disable the debugger; keyword on the current page. This feature is accessible via a new checkbox in the Breakpoints side panel labeled Pause on debugger statement, located next to the existing Pause on exceptions checkbox. By default, this option is enabled, meaning that the debugger statements are active unless manually disabled.
  • As part of our work on improving the accessibility of Firefox Developer Tools, we've unified the focus indicator across the toolbox. The focus indicator is now larger with improved contrast, featuring a white box-shadow for enhanced visibility on blue backgrounds. Adjustments have also been made to ensure clear visibility across shared components and frequently used panels, preventing overlap with element borders or backgrounds.
  • Web Platform:
  • The :has() selector is now supported. This allows authors to match an element that has, or "anchors", at least one element matching its relative selector.
  • The hanging and each-line keywords are now supported for the text-indent CSS property, offering more convenient paragraph layout options for styles such as bibliographies, poetry, etc.
  • The balance keyword is now supported for the text-wrap CSS property, which can improve the appearance of short multi-line text blocks such as long headings or captions by harmonizing the line lengths.
  • Lazy loading iframes are now supported (<iframe loading=lazy>). Lazy loading iframes are only loaded when visible, so non-critical iframes can load later when needed to speed up initial page loads, reduce initial network usage, etc.
  • Support has been added for tail call elimination in WebAssembly language to improve support for functional languages.

New in LibreWolf 120.0.1-1 (Dec 2, 2023)

  • Fixed:
  • Fixed a bug that was causing persistent startup slowdowns. (bug 1867095)
  • Fixed an issue that was causing 100% CPU usage on sites such as Google Maps. (bug 1866409)
  • Fixed an issue that was causing YouTube videos to show a green screen when hardware acceleration was enabled. (bug 1865928)
  • Fixed an issue where the status bar was still visible when viewing fullscreen video. (bug 1853896)
  • Fixed a startup crash affecting Linux users on some aarch64 systems with page sizes other than 4KB. (bug 1866025)

New in LibreWolf 120.0-1 (Nov 22, 2023)

  • New:
  • Firefox supports a new “Copy Link Without Site Tracking” feature in the context menu which ensures that copied links no longer contain tracking information.
  • Firefox now supports a setting (in Preferences ? Privacy & Security) to enable Global Privacy Control. With this opt-in feature, Firefox informs the websites that the user doesn’t want their data to be shared or sold.
  • Screenshot showing GPC preference
  • Firefox’s private windows and ETP-Strict privacy configuration now enhance the Canvas APIs with Fingerprinting Protection, thereby continuing to protect our users’ online privacy.
  • Firefox has enabled Cookie Banner Blocker by default in private windows for all users in Germany. Firefox will now auto-refuse cookies and dismiss annoying cookie banners for supported sites.
  • Firefox has enabled URL Tracking Protection by default in private windows for all users in Germany. Firefox will remove non-essential URL query parameters that are often used to track users across the web.
  • Firefox now imports TLS trust anchors (e.g., certificates) from the operating system root store. This will be enabled by default on Windows, macOS, and Android, and if needed, can be turned off in settings (Preferences ? Privacy & Security ? Certificates).
  • Keyboard shortcuts have now been added for editing and deleting a selected credential on about:logins. For editing - Alt + enter (Option + return on macOS) and for deleting - Alt + Backspace (Option + Delete on macOS).
  • Users on Ubuntu Linux now have the ability to import from Chromium when both are installed as Snap packages.
  • Picture-in-Picture now supports corner snapping on Windows and Linux - just hold Ctrl as you move the PiP window.
  • Fixed:
  • Various security fixes.
  • Enterprise:
  • You can find information about policy updates and enterprise specific bug fixes in the Firefox for Enterprise 120 Release Notes.
  • Developer:
  • Developer Information
  • The User Activation API has now been added, allowing JavaScript to check if the user currently is or has been active with the page (clicking, etc) with navigator.userActivation.
  • Early Hints Preconnect, the informational status code 103, is now enabled. This allows servers to send resource Link headers before the final HTTP response and improves performance on servers using this feature. (read more)
  • Users can now use an added devtools feature to simulate browser tabs to be offline.
  • The Style Editor panel now features a new "Pretty Print" button located in the footer of the panel, similar to the pretty print button found in the Debugger panel. This can be used to format stylesheets (e.g., those that are minified). The previous functionality, where minified files were automatically formatted, has been removed.
  • The Rules panel within the Inspector panel no longer displays colors in the new CSS Color 4 formats (e.g., OKLCH) as hexadecimal/named colors. This ensures that it matches the original values used.
  • Web Platform:
  • lh and rlh units can now be parsed and computed correctly as lengths. This allows authors to specify lengths in terms of the element's (or the root element's) line height.
  • WebAssembly GC is now enabled by default, which allows new languages, such as Dart or Kotlin, to run on Firefox. This makes it possible for reference cycles between the guest language and host browser to be collected.
  • Community Contributions:
  • With the release of Firefox 120, we are pleased to welcome the developers who contributed their first code change to Firefox in this release, 10 of whom were brand new volunteers!

  • If you're migrating your data from Chrome, Firefox now offers the ability to import some of your extensions as well.
  • As part of Total Cookie Protection, Firefox now supports the partitioning of Blob URLs, this mitigates a potential tracking vector that third-party agents could use to track an individual.
  • The visibility of fonts to websites has been restricted to system fonts and language pack fonts in Enhanced Tracking Protection strict mode to mitigate font fingerprinting.
  • The Storage Access API web standard was updated to improve security while mitigating website breakages and further enabling the phase out of third-party cookies in Firefox.
  • Encrypted Client Hello (ECH) is now available to Firefox users, delivering a more private browsing experience. ECH extends the encryption used in TLS connections to cover more of the handshake and better protect sensitive fields. Read more about the launch of ECH on Mozilla Distilled.

  • Enables overlay of software-decoded video on Intel GPUs in Windows. Improves video down scaling quality and reduces GPU usage.
  • Private windows and ETP set to strict will now include email tracking protection. This will make it harder for email trackers to learn the browsing habits of Firefox users. You can check the Tracking Content in the sub-panel on the shield icon panel.

  • GPU sandboxing has been enabled on Windows.
  • Note: A bug in the popular X-Mouse Button Control (XMBC) tool may cause mouse wheel scrolling to stop working. The author(s) are working on an update. Meanwhile, scrolling can be restored by reconfiguring XMBC: either disable the Make scroll wheel scroll window under cursor option in the global settings, or enable the Disable scroll window under cursor option if using a custom profile for Firefox.
  • On Windows, third-party modules can now be blocked from injecting themselves into Firefox, which can be helpful if they are causing crashes or other undesirable behavior.

New in LibreWolf 105.0.1-1 (Sep 26, 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.

New in LibreWolf 104.0.2-1 (Sep 12, 2022)

  • Fixed:
  • Fixed a bug making it impossible to use touch or a stylus to drag the scrollbar on pages.
  • Fixed an issue causing some users to crash in out-of-memory conditions.
  • Fixed an issue that would sometimes affect video & audio playback when loaded via a cross-origin iframe src attribute.

  • Do you always forget something? Required fields are now highlighted in PDF forms.
  • Improved performance on high-refresh rate monitors (120Hz+).
  • Enjoying Picture-in-Picture subtitles feature? It just got better: you can now change subtitles font size directly from the PiP window. Additionally, PiP subtitles are now available at Funimation, Dailymotion, Tubi, Hotstar, and SonyLIV.
  • Buttons in the Tabs toolbar can now be reached with Tab, Shift+Tab, and Arrow keys. View this article for additional details.
  • Windows' "Make text bigger" accessibility setting now affects all the UI and content pages, rather than only applying to system font sizes.
  • Rejoice! You can now conveniently access Firefox, which will now be pinned to the Windows taskbar during installation on Windows 10 and 11. (This will also allow for Firefox to be launched quicker after installing.)
  • Fixed:
  • Non-breaking spaces are now preserved—preventing automatic line breaks—when copying text from a form control.
  • Fixed WebGL performance issues on NVIDIA binary drivers via DMA-Buf on Linux.
  • Fixed an issue in which Firefox startup could be significantly slowed down by the processing of Web content local storage. This had the greatest impact on users with platter hard drives and significant local storage.
  • Various security fixes.
  • Changed:
  • Removed a configuration option to allow SHA-1 signatures in certificates: SHA-1 signatures in certificates—long since determined to no longer be secure enough—are now not supported.
  • Web Platform:
  • Your information now has increased protection from online tracking via Total Cookie Protection enabled by default. All third-party cookies are now isolated into partitioned storage.

New in LibreWolf 98.0 (Mar 10, 2022)

  • New:
  • Firefox has a new optimized download flow. Instead of prompting every time, files will download automatically. However, they can still be opened from the downloads panel with just one click. Easy!
  • You’ll find you have a number of options, including:
  • Always Open Similar Files: Make Firefox automatically open downloaded files of the same type with the system default application.
  • Show In Folder: Open the folder that contains your downloaded files.
  • Go To Download Page: Surfaces the download reference page even after leaving the site or closing the tab.
  • Copy Download Link: Copy the download link to share it, save it, or for any applicable use.
  • Delete: You can now delete downloaded files directly from the download panel and other download views using the context menu.
  • Remove From History: Remove a file from your list of downloaded files.
  • Clear Preview Panel: Clear the list of downloaded items in the preview panel that opens when you start a download.
  • In this release, you’ll also see that Firefox no longer asks what to do for each file by default. You won’t be prompted to choose a helper application or save to disk before downloading a file unless you have changed your download action setting for that type of file.
  • And now, every time you start a download, Firefox will automatically bring up the Downloads panel by default. This means you’ll experience minimal interruptions and easily find your downloaded files. Plus, to avoid having to close it several times, the panel won't show if there are multiple downloads in progress.
  • You can now click on a file in the Downloads panel to open it even before it has finished downloading. Firefox will open the file as soon as it is available. Firefox: saving you time and helping you get back to what you care about!
  • Any files you download will be immediately saved on your disk. Depending on the current configuration, they’ll be saved in your preferred download folder, or you’ll be asked to select a location for each download. Windows and Linux users will find their downloaded files in the destination folder. They’ll no longer be put in the Temp folder.
  • Firefox allows users to choose from a number of built-in search engines to set as their default. In this release, some users who had previously configured a default engine might notice their default search engine has changed since Mozilla was unable to secure formal permission to continue including certain search engines in Firefox.
  • Fixed:
  • Now, you can set a default app to open a file type. Choose the application you want to use to open files of a specific type in your Firefox settings.
  • After updating to Firefox version 98, "Always ask" download actions will now be reset.
  • 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 98 Release Notes.
  • Developer:
  • The Compatibility sidebar panel in the DevTools Inspector already available on pre-release channels will become available on the release channel in version 98 . It provides compatibility warnings for the CSS properties used on the selected element, as well as for the overall page.
  • Developers may use it to detect web-compatibility issues early, without having to test in each browser. All compatibility data are pulled from MDN.
  • Event listeners for a given node can now be disabled from the Inspector Event Tooltip, in the markup view. Also, The "event" badge style is updated when at least one event is disabled to remind the user that something was changed.
  • New UI in the Browser Toolbox to toggle Fluent pseudolocalization bidi / accented
  • “Ignore line” context menu entry added in the debugger editor gutter when devtools.debugger.features.blackbox-lines is true. Also, there is a better “Ignore source” icon and editor background colors for ignored lines.
  • Auto-open devtools for tabs opened via window.open (behind devtools.popups.debug). On a page where you already have DevTools opened, if a new tab is created via window.open, the toolbox will automatically move to the new tab, with the new document selected in both the iframe picker and the context selector
  • Web Platform:
  • The <dialog> HTML element already available on pre-release channels will become available on the release channel in version 98.
  • Form associated custom elements will become available on the release channel in version 98. This allows web authors to define and create custom elements that can be participated in form submission.
  • The hyphenate-character CSS property can be used to set a string that is used instead of a hyphen character (-) at the end of a hyphenation line break.

In other words, if a colorway is “enabled” in the add-ons manager, that colorway is yours forever. Read more about colorway updates here.
