In addition to streamlining data categories, the new dialog also provides insights into the site data size corresponding to the selected time range. ![screenshot of the Clear browsing data and cookies dialog. Demonstrating the new features of clearing data within a selected time range and the size of that data](https://www.mozilla.org/media/img/firefox/releasenotes/note-images/128_clear_site_data.png) * Firefox now supports playback of protected content from streaming sites like Netflix while in Private Browsing mode. * Firefox now supports the experimental [Privacy Preserving Attribution API](https://support.mozilla.org/kb/privacy-preserving-attribution), which provides an alternative to user tracking for ad attribution. This experiment is only enabled via [origin trial](https://wiki.mozilla.org/Origin_Trials) and can be disabled in the new Website Advertising Preferences section in the Privacy and Security settings. * On macOS, microphone capture through getUserMedia will now use system-provided voice processing when applicable, improving audio quality. * Firefox is now available in the Saraiki (skr) language. ![](https://www.mozilla.org/media/protocol/img/icons/check.6ae3794b67ae.svg) ### Fixed * Firefox now proxies DNS by default when using SOCKS v5, avoiding leaking DNS queries to the network when using SOCKS v5 proxies. * Various [security](https://www.mozilla.org/security/advisories/mfsa2024-29/) fixes. ![](https://www.mozilla.org/media/protocol/img/icons/features.e3de7d037f25.svg) ### Changed * Firefox now supports rendering more `text/*` file types inline, rather than requiring them to be downloaded to be viewed. * The root certificate used to verify add-ons and signed content has been renewed to avoid upcoming expiration. ![](https://www.mozilla.org/media/protocol/img/icons/enterprise.fcddd37abbfc.svg) ### Enterprise * You can find information about policy updates and enterprise specific bug fixes in the [Firefox for Enterprise 128 Release Notes](https://support.mozilla.org/kb/firefox-enterprise-128-release-notes). ![](https://www.mozilla.org/media/protocol/img/icons/developer.fc7d2d65df74.svg) ### Developer * [Developer Information](https://developer.mozilla.org/docs/Mozilla/Firefox/Releases/128) * [CSS rules specificity](https://developer.mozilla.org/docs/Web/CSS/Specificity) is now displayed in a tooltip when hovering a CSS rule selector in the Inspector Rules view. This can help web developers understand why a given rule is applied before another. ![screenshot of the specificity tooltip when hovering a CSS Rule selector in the Inspector Rules view](https://www.mozilla.org/media/img/firefox/releasenotes/note-images/128_devtools_css_specificity.png) * The Inspector panel now flags a custom property declaration as invalid when the value does not match the registered custom property definition. As shown in the screenshot below, the declaration of a custom property, `--b`, expecting a `<length>` value syntax (e.g., `10px`), is instead used with a color specified. An exclamation icon appears next to it with a tooltip explaining the error. ![screenshot of an example of the exclamation icon beside an invalid custom property declaration and a tooltip explaining the error](https://www.mozilla.org/media/img/firefox/releasenotes/note-images/128_devtools_invalid_property.png) * Improvements have been made to Inactive CSS. A warning is now displayed when `column-span` is used on elements outside of multi-column containers and when properties only applying to replaced elements are used on non-replaced elements. ![](https://www.mozilla.org/media/protocol/img/icons/globe.b1488be03021.svg) ### Web Platform * [Resizeable ArrayBuffers](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer/resize) and [Growable SharedArrayBuffers](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer/grow) are now supported in SpiderMonkey. This allows the size of an ArrayBuffer to be changed without having to allocate a new buffer and copy data into it. * The [setCodecPreferences](https://www.w3.org/TR/webrtc/#dom-rtcrtptransceiver-setcodecpreferences) method allows applications to disable the negotiation of specific codecs (including RTX/RED/FEC). It also allows an application to cause a remote peer to prefer the codec that appears first in the list for sending. * The Accept header for images and documents was [changed](https://developer.mozilla.org/docs/Web/HTTP/Content_negotiation/List_of_default_Accept_values) to better align with the Fetch standard and other browsers. * Support was added for `@property` and the [CSS properties-and-values API](https://developer.mozilla.org/docs/Web/API/CSS_Properties_and_Values_API). * A new `bytes()` method is provided on many objects like Request/Response and Blob that provides a convenient way of [getting an Uint8Array typed array](https://github.com/w3ctag/design-principles/issues/463). * The [relative color syntax](https://developer.mozilla.org/docs/Web/CSS/CSS_colors/Relative_colors) is now supported in CSS color functions. This allows to create colors based on other colors. ![](https://www.mozilla.org/media/img/firefox/releasenotes/community.e1943a67466a.svg) ### Community Contributions * With the release of Firefox 128, we are pleased to welcome the developers who contributed their first code change to Firefox in this release, 9 of whom were brand new volunteers!
