Almost a month after releasing version 142, Mozilla has launched Firefox 143, the latest update to its popular open-source web browser, now available for download.
One of the more noticeable changes is the addition of camera previews in the permission dialog. Now, when a site asks for access, users can see which camera they’re about to allow, which should make switching between multiple devices a little less frustrating.
Android users also get several quality-of-life improvements. Download progress can now be tracked in real time, with options to pause, resume, retry, or cancel directly from the Downloads screen. Plus, persistent notifications now behave correctly after a restart, and DNS over HTTPS (DoH) can finally be configured in the settings UI.
Additionally, in private browsing mode, Firefox will now ask whether downloaded files should be kept or deleted, with the option to set a preference in settings.
On desktop, Firefox introduces support for running websites as standalone web apps on Windows. These can be pinned and launched as simplified windows directly from the taskbar, while still allowing access to extensions. This feature is currently not available for versions installed through the Microsoft Store.
On the privacy side, fingerprinting protection has been expanded to cover additional system attributes, further limiting the ability of websites to track users through subtle system details.
Developers get a few updates as well. Unchecking the “Group Similar Messages” setting now ensures all console messages are displayed individually. At the same time, web platform changes include support for xHE-AAC audio playback on Windows 11 (22H2+), macOS, and Android 9 or newer.
Firefox also updates its CSS Grid implementation for better spec compliance, allows styling of <details> elements with a new ::details-content pseudo-element, and extends <input type=color> to recognize CSS <color> formats in addition to hex values.
Those eager to immediately download the latest version of Firefox can do so directly from Mozilla’s server.
Windows and macOS users can expect an over-the-air update within the next days. Users of rolling-release Linux distributions should look for Firefox 143 as an update in their repositories over the next few days.
