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.

The extension is still broken (for folks who block pop-ups in Firefox https://t.co/RLjrjgb9Vo), so I guess I’ll just use your bookmarklet instead. 😂
