See what landed recently in Firefox Nightly!

Fixed address bar results covering the address bar in macOS full screen when the menu bar was revealed.

Fixed context menu items sometimes appearing blank, without their labels, after Firefox was updated.

Fixed some images on Firefox for Android not showing the image description when long-pressing the image.

Fixed Firefox for Android not switching between light and dark theme to match the device if the setting changed while Firefox was still open.

When configured to restore previous sessions, Firefox now restores windows to their saved positions on GNOME 51 and later, matching existing support on KDE Plasma 6.8+.

Starting with Firefox 159, Firefox Nightly on macOS selects the word or link under the pointer when right-clicking like other macOS apps.

Starting with Firefox 161, the search engine button in the address bar is always visible in Firefox Nightly, not only when the address bar is focused.

Starting with Firefox 160, Nightly builds take the transforms of an anchor element into account when positioning elements with CSS anchor positioning.

Starting with Firefox 161, Firefox Nightly supports the CSS text-autospace-size property, which sets the width of the space text-autospace: normal adds between ideographic text, such as Chinese or Japanese, and other text.

Starting with Firefox 162, Firefox Nightly now supports the ident() arbitrary substitution function, which allows authors to dynamically construct identifiers by concatenating other values. The ident() function can be used wherever an <ident> is accepted.

Firefox now supports the CSS Typed Object Model, which lets scripts read and write CSS values as typed JavaScript objects instead of strings. Color values, such as CSSColorValue, are not supported yet.

Firefox now supports streaming uploads with the Fetch API, allowing web applications to send request bodies incrementally using a ReadableStream without buffering the entire body first.

Starting with Firefox 161, Firefox Nightly supports the CSS margin-trim property for block containers, which removes the margins of child elements at the container's edges.
