 ## Changes for web developers

 ### CSS
 
-- The `inset-area` CSS property has been renamed to {{CSSXRef("position-area")}} in preparation for further implementation of [Anchor Positioning](/en-US/docs/Web/CSS/CSS_anchor_positioning), so at present this property is only used internally for parsing values. The set of Anchor Positioning features are being progressively rolled out behind a preference. See [Experimental features in Firefox: CSS Anchor Positioning](/en-US/docs/Mozilla/Firefox/Experimental_features#css_anchor_positioning) for more information. ([Firefox bug 1909358](https://bugzil.la/1909358) and [Firefox bug 1838746](https://bugzil.la/1838746)).

 ### JavaScript
 
-- Support for synchronous iterator helpers, including: {{jsxref("Iterator.prototype.drop()")}}, {{jsxref("Iterator.prototype.every()")}}, {{jsxref("Iterator.prototype.filter()")}}, {{jsxref("Iterator.prototype.find()")}}, {{jsxref("Iterator.prototype.flatMap()")}}, {{jsxref("Iterator.prototype.forEach()")}}, {{jsxref("Iterator.prototype.map()")}}, {{jsxref("Iterator.prototype.reduce()")}}, {{jsxref("Iterator.prototype.some()")}}, and {{jsxref("Iterator.prototype.take()")}}. These allow `Array`-like operations on iterators without having to create intermediate `Array` objects, and can also be used with very large data sets where creating an intermediate `Array` would not even be possible. For more information see [Iterator helpers](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Iterator#iterator_helpers) in the `Iterator` interface. ([Firefox bug 1896390](https://bugzil.la/1896390)).

+- Support for synchronous iterator helpers has been added, including: {{jsxref("Iterator.prototype.drop()")}}, {{jsxref("Iterator.prototype.every()")}}, {{jsxref("Iterator.prototype.filter()")}}, {{jsxref("Iterator.prototype.find()")}}, {{jsxref("Iterator.prototype.flatMap()")}}, {{jsxref("Iterator.prototype.forEach()")}}, {{jsxref("Iterator.prototype.map()")}}, {{jsxref("Iterator.prototype.reduce()")}}, {{jsxref("Iterator.prototype.some()")}}, and {{jsxref("Iterator.prototype.take()")}}.

([Firefox bug 1896390](https://bugzil.la/1896390)).
 
 ### HTTP
 
 - A {{httpheader("Set-Cookie")}} HTTP header with the attribute value of [`SameSite=None`](/en-US/docs/Web/HTTP/Headers/Set-Cookie#none) must now also include the [`Secure`](/en-US/docs/Web/HTTP/Headers/Set-Cookie#secure) attribute. This ensures that cookies set with `SameSite=None` are only ever sent over HTTPS channels. In addition, since Firefox interprets an unspecified `SameSite` value as `SameSite=None`, cookies that don't specify `SameSite` will have the same restriction. ([Firefox bug 1909673](https://bugzil.la/1909673)).
 - [Cookies Having Independent Partitioned State (CHIPS)](/en-US/docs/Web/Privacy/Privacy_sandbox/Partitioned_cookies), or "partitioned cookies", are now supported.
-  This feature allow developers to opt a cookie into partitioned storage using the [`partitioned`](/en-US/docs/Web/HTTP/Headers/Set-Cookie#partitioned) directive of the {{HTTPHeader("Set-Cookie")}} HTTP header. When set, cookies have separate storage for each top-level site, and can only be read within the same top-level site they were set on and its subdomains. This blocks cross-site tracking, while still enabling legitimate uses of third-party cookies such as persisting state of embedded maps or chat widgets across different subdomains of a site. ([Firefox bug 1908160](https://bugzil.la/1908160)).

 ### APIs
 
-- The {{domxref('PointerEvent.altitudeAngle','altitudeAngle')}} and {{domxref('PointerEvent.azimuthAngle','azimuthAngle')}} properties of the {{domxref('PointerEvent')}} interface are supported, providing the angle between the pointer/stylus and the screen (X-Y plane), and the rotation of the stylus over the screen relative to its x-axis, respectively. ([Firefox bug 1656377](https://bugzil.la/1656377)).

([Firefox bug 1656377](https://bugzil.la/1656377)).
 - [Text fragments](/en-US/docs/Web/URI/Fragment/Text_fragments) are now supported, allowing users to link to and highlight specific portions of text in a web page. This feature uses a particular syntax in the [URL fragment](/en-US/docs/Web/URI/Fragment) that identifies the target based on patterns in the rendered text.
-  Website developers can also use the existence of the {{domxref("Document.fragmentDirective")}} property (an instance of the {{domxref("FragmentDirective")}} interface) to feature check for text fragment support, and the {{CSSxRef("::target-text")}} pseudo element to select and style text that has been selected using a text fragment link. ([Firefox bug 1914877](https://bugzil.la/1914877))
-- The {{domxref('Document/caretPositionFromPoint','caretPositionFromPoint()')}} method of the {{domxref("Document")}} interface has been updated so that it can return the text node and offset for a caret position within a shadow DOM, provided the shadow root corresponding to the point has been supplied to the method. {{domxref("ShadowRoot")}} objects can be passed to the method using the `shadowRoots` property of the newly added `options` argument. ([Firefox bug 1914596](https://bugzil.la/1914596)).

 ### WebAssembly
 
 - The new exception reference with the value of `exnref` can now be used to help with [exception handling](/en-US/docs/WebAssembly/JavaScript_interface/Exception) between WebAssembly and JavaScript in both directions. ([Firefox bug 1908375](https://bugzil.la/1908375)).

 ### WebDriver conformance (WebDriver BiDi, Marionette)
 
 #### General
 
-- For both WebDriver Classic and BiDi the `keyUp` and `keyDown` actions will no longer accept multiple characters for the `value` ([Firefox bug 1910352](https://bugzil.la/1910352)).
+- For both WebDriver Classic and BiDi, the `keyUp` and `keyDown` actions will no longer accept multiple characters for the `value`. ([Firefox bug 1910352](https://bugzil.la/1910352)).
 
 #### WebDriver BiDi
 
-- Added support for remaining arguments of `network.continueResponse` command:
-  - The cookies and headers arguments ([Firefox bug 1853887](https://bugzil.la/1853887)).
-  - The `statusCode` (e.g., 200, 304) and `reasonPhrase` (e.g., "OK", "Not modified") arguments ([Firefox bug 1913737](https://bugzil.la/1913737)).
-- The `browsingContext.navigate` command will now return if the `wait` argument is `none` and a beforeunload prompt is triggered ([Firefox bug 1763134](https://bugzil.la/1763134)).
-- The `browsingContext.navigate` command will return an `unknown error` in all cases where a navigation failure occurs, as required by the specification ([Firefox bug 1905083](https://bugzil.la/1905083)).
-- The `session.new` command will no longer include the `unhandledPromptBehavior` capability in its response if it was not specified by the client as an argument ([Firefox bug 1909455](https://bugzil.la/1909455)).

 ## Changes for add-on developers
 
-- {{WebExtAPIRef("tabs.onUpdated")}} is now triggered when `openerTabId` is changed through `tabs.update()` ([Firefox bug 1409262](https://bugzil.la/1409262)).
-- {{WebExtAPIRef("tabs.update")}} now accepts `openerTabId` set to `-1` to clear `openerTabId` ([Firefox bug 1409262](https://bugzil.la/1409262)).

 ## Experimental web features
 
 These features are newly shipped in Firefox 131 but are disabled by default. To experiment with them, search for the appropriate preference on the `about:config` page and set it to `true`. You can find more such features on the [Experimental features](/en-US/docs/Mozilla/Firefox/Experimental_features) page.
 
-- **Regular expression (?ims-ims:...) modifiers:** `javascript.options.experimental.regexp_modifiers`
+- **Regular expression (?ims-ims:...) modifiers:** `javascript.options.experimental.regexp_modifiers`.
 
-  The [(?ims-ims:...)](/en-US/docs/Web/JavaScript/Reference/Regular_expressions/Modifier) regular expression modifiers allow you to make changes to only take effect in a specific part of a regex pattern. ([Firefox bug 1899813](https://bugzil.la/1899813)).

-  The `microphone` and `camera` [permissions](/en-US/docs/Web/API/Permissions_API) can now be used in the {{domxref("Permissions.query()")}} method to test whether access to the corresponding hardware have been granted, denied, or still requires user approval ([Firefox bug 1609427](https://bugzil.la/1609427), [Firefox bug 1915222](https://bugzil.la/1915222)).
