Like most other responsible web users I went and downloaded the brand spanking new Firefox 1.5 yesturday.  Whenever I download an install a new version of Firefox, I have to reload all my extensions.  This can be a tremendous pain because of version incompatibilities. My saving grace is that I know that most of the extensions will come out with versions compatible with Firefox 1.5 in the near future.  When I say most, I mean all except the Venkman Javascript Debugger.   The Venkman Javascript Debugger is a beautiful piece of code that literally enables me to act like a wizard of AJAX.  People who are not aware of Venkman are dazzled by how fast I can debug a piece of javascript and subsequently pay me money to do so.   When Venkman  didn't work for Firefox 1.5, I quickly started hacking and have produced an UNOFFICIAL version that does.  It's linked below. UPDATE: Getahead has a version that actually works, turns out my version doesn't. Venkman Home Page Unoffical Venkman that works with Firefox 1.5
