Firebug 1.1 betas now available
Firebug is one of those web development tools that you can’t just live without. It’s kind of funny just thinking how hard life used to be before we had this wonderful extension available.
Even though this extension is pretty much perfect, even more so when you also install the YSlow add-on, there is work going on right now on the new 1.1 version of Firebug. You can download a beta version here: http://getfirebug.com/releases/allReleases.html
