Lighthouse bookmarklet

I use Firefox. You should too. It���s fast, secure, and more privacy-focused than the leading browser from the big G.

When it comes to web development, the CSS developer tooling in Firefox is second-to-none. But when it comes to JavaScript and network-related debugging (like service workers), Chrome���s tools are currently better than Firefox���s (for now). For example, Chrome has a tab in its developer tools that lets you run Lighthouse on the currently open tab.

Yesterday, I got the Calibre newsletter, which always has handy performance-related links from Karolina. She pointed to a Lighthouse extension for Firefox. ���Excellent!���, I thought, and I immediately installed it. But I had some qualms about installing a plug-in from Google into a browser from Mozilla, particularly as the plug-in page says:

This is not a Recommended Extension. Make sure you trust it before installing

Well, I gave it a go. It turns out that all it actually does is redirect to the online version of Lighthouse. ���Hang on���, I thought. ���This could just be a bookmarklet!���

So I immediately uninstalled the browser extension and made this bookmarklet:

Lighthouse

Drag that up to your desktop browser���s bookmarks toolbar. Press it whenever you���re on a site that you want to test.
