The Mozilla Firefox 129 open-source, free, and cross-platform web browser is now available for download ahead of its official release on August 6th, 2024, so it’s time to look at the new features and improvements.
Mozilla Firefox 129 is a minor update that only improves the Reader View with a “Text and layout” menu that replaces the “Type controls” menu and features new options for setting character spacing, word spacing, and text alignment for a more accessible reading experience, and a new “Theme” menu with additional Contrast and Gray options allowing users to select their own custom colors for text, background, and links.

On top of that, Firefox 129 replaces HTTP with HTTPS as the default protocol in the address bar for non-local sites, enables the address autofill feature for users in France and Germany, and adds support for multiple languages in the same document spoken in macOS VoiceOver.
For web developers, Firefox 129 brings support for querying the encryption key system config in the mediaCapabilities.decodingInfo() API, support for @starting-style to define styles that are applied to an element when it is first rendered, and support for the transition-behavior CSS property.
It also adds support for Float16Array typed arrays and new DataView methods for reading and setting Float16 values, as well as a Math.f16round() static method for rounding numbers to 16 bits, as well as support for the textInput event.
As mentioned before, Mozilla plans to officially announce the Firefox 129 release tomorrow, August 6th, along with Firefox 128.1 ESR and Firefox 115.14 ESR versions. However, you can download the official binaries for 64-bit or 32-bit systems from Mozilla’s download server, or install the official DEB package from Mozilla’s APT repository.
