The link for the IE Developer Toolbar in the original article carries a date of September 19, 2005 in the URL. Which makes sense, because it was demonstrated at PDC 2005, which was the previous week. Link: http://betanews.com/2005/09/19/microsoft-issues-ie-developer-toolbar/ http://betanews.com/2005/09/19/microsoft-issues-ie-developer... Note also that the release notes for Firebug v0.2 state: "This is a very early release - the code is only a few days old." Whereas the IE Developer Toolbar probably began a couple of months before its first release. So even by looking at the first mention on the web, we're comparing a days-old Firebug to a fairly-complete IE Developer Toolbar.
