What it does

The story of Firefox and Firebug are synonymous with the rise of the web. We fought the good fight and changed how developers inspect HTML and debug JS in the browser. Firebug ushered the Web 2.0 era. Today, the work pioneered by the Firebug community through the last 12 years lives on in Firefox Developer Tools. Switch to the latest version of Firefox and see the very latest devtools updates. There are too many contributors to count but here are the names that come to mind.

    Hi HN! I've been working lately on unifying firefox configuration. Many people work on creating custom `userChrome.css` files and modules, browser user scripts, etc, but it's hard to actually use these a lot of the time. It usually involves cloning a repo, finding a folder and lots of copy paste. My tool (firebuilder) has an interactive CLI to select what to apply, (e.g. firefox hardening, custom CSS, etc) then creates a brand new profile folder for you.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
