Firebug caught people’s attention — and more than a million loyal fans still use it today.
So it’s sad that Firebug is now reaching end-of-life in the Firefox browser, with the release of Firefox Quantum (version 57) next month. The good news is that all the capabilities of Firebug are now present in current Firefox Developer Tools.
The story of Firefox and Firebug is 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 in the Web 2.0 era. Today, the work pioneered by the Firebug community over the last 12 years lives on in Firefox Developer Tools.
