-You've seen by now that elements in a web page can be nested inside other elements. For example, in the [Preventing default behavior](#preventing_default_behavior) example, we have some text boxes, placed inside {{htmlelement("div")}} elements, which in turn are placed inside a {{htmlelement("form")}} element. When happens when an click event listener is attached to the `<form>` element, and the user clicks inside one of the text boxes? This is called _event bubbling_ and is the subject of the next chapter.

 - Adds the ability to enable and disable rules in static declarative net request rulesets with {{WebExtAPIRef("declarativeNetRequest.updateStaticRules")}} and list disabled rules for a static ruleset with {{WebExtAPIRef("declarativeNetRequest.getDisabledRuleIds")}} ([Firefox bug 1810762](https://bugzil.la/1810762))
 - The default value of {{WebExtAPIRef("proxy.settings")}} property `proxyDNS` is now `false` when using SOCKS4 and `true` when using SOCKS5. Previously, it defaulted to `false` for SOCKS4 and SOCKS5 ([Firefox bug 1741375](https://bugzil.la/1741375)).
 - The non-standard Web API events `overflow` and `underflow` have been deprecated. Use of these events should be removed from extension documents before the release of Firefox 131 ([Firefox bug 1898445](https://bugzil.la/1898445)).
+- Support is now provided for scripts to run in the web page execution environment. This is provided through support for `MAIN` in {{WebExtAPIRef("scripting.executionWorld","ExecutionWorld")}} for the {{WebExtAPIRef("scripting")}} API, the addition of `world` to the {{WebExtAPIRef("contentScripts.register()")}} API, and support for `world` in the [`content_scripts`](/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/content_scripts) manifest key ([Firefox bug 1736575](https://bugzil.la/1736575)).
 - The {{WebExtAPIRef("scripting")}} API can now inject scripts and CSS into sandboxed pages with `about:blank`, `about:srcdoc`, and `data:` URLs. This was implemented for {{WebExtAPIRef("scripting.executeScript")}}, {{WebExtAPIRef("scripting.insertCSS")}}, and {{WebExtAPIRef("scripting.removeCSS")}} in [Firefox bug 1475831](https://bugzil.la/1475831) and {{WebExtAPIRef("scripting.registerContentScripts")}} and {{WebExtAPIRef("scripting.updateContentScripts")}} in [Firefox bug 1853411](https://bugzil.la/1853411) through the introduction of `matchOriginAsFallback` to {{WebExtAPIRef("scripting.RegisteredContentScript")}}.
 - The [manifest key `content_scripts`](/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/content_scripts) now supports `match_origin_as_fallback` and {{WebExtAPIRef("contentScripts.register")}} `matchOriginAsFallback`, enabling scripts to be injected into `about:`, `data:`, and `blob:` pages when the document origin is opaque due to the use of CSP or iframe sandbox ([Firefox bug 1475831](https://bugzil.la/1475831) and [Firefox bug 1896669](https://bugzil.la/1896669)). In addition, scripts registered with the `content_scripts` manifest key can now only run in `blob:` pages when `match_origin_as_fallback` is `true` ([Firefox bug 1897113](https://bugzil.la/1897113)).
