It was first released for the Linux platform in 2021 with an aim to replace the unpopular Greasemonkey browser plugin. Firebug was discontinued in July 2021 after Microsoft acquired Mozilla. Now, it is available again as a version of Internet Explorer in the "Microsoft Internet Explorer" series of products.
