Cypress has introduced support for automating Firefox using the WebDriver BiDi protocol starting from Cypress 14.1.0. This change moves away from the previously used Chrome DevTools Protocol (CDP), aligning with Firefox's future direction and providing improved browser automation. Users can still opt to use CDP with the `FORCE_FIREFOX_CDP=1` environment variable, though CDP support will be removed in Cypress 15. Ongoing collaboration with browser vendors aims to enhance and expand automation capabilities.
