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 and was released as an extension for Google Chrome in 2016.

Now that the Mozilla Firefox Lighthouse Extension has been released, Firefox users can perform pages peed tests in their preferred browser.

For those not familiar with Lighthouse, it is a browser extension that allows you to generate a report about a web page's performance using the Google PageSpeed API. This API includes real-time data from Google's Chrome User Experience Report and lab data from Lighthouse.

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.

For example, below is a Lighthouse report for a Google search results page. As you can see, it provides a score ranging from 0-100 for performance, accessibility, best practices, and SEO categories.
