Google has brought its popular Lighthouse extension used by over 400,000 users to Mozilla Firefox so that web developers can test the browser’s performance against submitted web pages. Lighthouse is an open-source tool for testing the performance of web pages through Google’s PageSpeed Insights API. The report will display information on how fast the page loads, what issues are affecting its performance and will offer suggestions on how to increase the page’s performance, accessibility, and SEO. Mozilla Firefox users can perform pages peed tests in their preferred browser.
