 To gauge the capabilities of WebDriver BiDi, we utilized the comprehensive [Puppeteer test suite](https://puppeteer.github.io/ispuppeteerwebdriverbidiready/)
 
-- For Firefox, there are currently under [60](https://puppeteer.github.io/ispuppeteerwebdriverbidiready/firefox-delta.json) failing tests compared to the CDP implementation, while over [82](https://puppeteer.github.io/ispuppeteerwebdriverbidiready/firefox-delta.json) new tests successfully utilize WebDriver BiDi, demonstrating its growing potential.
-- For Chrome, around 68% of tests pass with WebDriver BiDi, indicating room for improvement compared to the CDP-based approach.
