 By default, we will launch Firefox headlessly during `cypress run`. To run
 Firefox headed, you can pass the `--headed` argument to `cypress run`.
 
+##### Webdriver BiDi and CDP Deprecation
+
+:::info
+
+Since Firefox 129, Chrome DevTools Protocol (CDP) has been [deprecated in Firefox](https://fxdx.dev/deprecating-cdp-support-in-firefox-embracing-the-future-with-webdriver-bidi/).
+In Firefox 135 and above, Cypress defaults to automating the Firefox browser with WebDriver BiDi.
+Cypress will no longer support CDP within Firefox in the future and is planned for removal in Cypress 15.
+
+If CDP still needs to be used, you can force enablement via the `FORCE_FIREFOX_CDP=1` environment variable, regardless of Firefox version. For example:
+
+```bash
+FORCE_FIREFOX_CDP=1 npx cypress run --browser firefox
+```
