Firefox 143 is out with the ability to pin sites to taskbar, Copilot integration, and more

Mozilla has released Firefox 143 for all users in the Release Channel. At the moment, the update is available via Mozilla's FTP, with general availability expected tomorrow. Firefox 143 introduces a bunch of useful features, primarily for Windows users, but there is something for everyone else.

With Firefox 143, Windows users can pin websites as web apps to the taskbar and run them in windows without the Firefox UI. A similar feature has been available in Edge and other browsers for quite a while, and Firefox is finally following suit. Keep in mind that this feature is not available in the Microsoft Store version of the browser.

Another Microsoft-related addition in Firefox 143 is Copilot. You can now have Microsoft's AI assistant in the sidebar to use it alongside your current tab. Additionally, Firefox now supports Windows UI Automation for improved accessibility, especially for built-in tools like Voice Access, Text Cursor, and Narrator.

Other useful changes in Firefox 143 include the ability to auto-delete files downloaded when in Private Browsing mode, xHE-AAC playback support on Windows 11 (version 22H2 and newer), macOS, and Android (verison 9 and newer), webcam preview in camera access prompt (useful if you have several cameras and you want to ensure the website uses the correct one), improved Fingerprinting Protection, and more features for the address bar. The latter can now show important dates in events if you live in the United States, the United Kingdom, Germany, France, or Italy.

As usual, the latest Firefox release includes security updates, various changes for developers, and a series of enterprise-related changes. Security updates will be available on this page (once it is live), and enterprise release notes will be here.

If you do not want to wait for Mozilla to ship Firefox 143 using its regular update channel, you can download the latest Firefox release from the company's FTP using this link. The browser is also available on Neowin's software page.
