This awesome little application will walk you through creating windows install CDs that you can tune in hundreds of ways. It makes slipstreaming SPs a piece of cake. You can also preload drivers for targets installs. Making unattended install discs is simple. I've found it quite useful for trimming out all of the $#!+ that you really don't need making for an install of XP that really screams.
There are some work arounds cited in the bug tracker referenced but they include shutting off critically useful parts of Firebug. This is only an issue for people using recent Firefox and Firebug versions. I'm keeping a close eye on this one and will keep you all updated.
Joshua and others have requested this in the past. I'm throwing it here in Diigo so others can benefit as well. It isn't Firebug by a longshot, but it is much better than nothing at all. I prefer to use this over Microsoft Script Debugger when debugging in IE. As noted though, it doesn't work with IE8. IE does however include its own developer tools.
