##### Webdriver BiDi and CDP Deprecation

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/).
198
+
In Firefox 135 and above, Cypress defaults to automating the Firefox browser with WebDriver BiDi.
199
+
Cypress will no longer support CDP within Firefox in the future and is planned for removal in Cypress 15.

+
201
+
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:
202
+
203
+
```bash
204
+
FORCE_FIREFOX_CDP=1 npx cypress run --browser firefox
205

```
