Using lighthouse cli with firefox as a headless browser

[thearunkumar]

Hi

I'm trying to run lighthouse cli and measure the performance and while it works fine with chrome-launcher, I am actually looking for running using a firefox headless browser mode as the application runs mainly on firefox.

Is there a way to achieve that using karma-firefox-launcher or something similar?

Any guidance is appreciated.

Thanks,

No. Lighthouse can only test pages using Chrome.

Even with puppeteer-firefox, it doesn't work?

Lighthouse requires a Chrome DevTools protocol connection to analyze to the page. We can't use Firefox's protocol even with puppeteer.
