The old version actually worked fine with 3.6, but you had to have the "Add-on Compatibility Reporter" add-on installed to disable Firefox's compatibility checking so it could load and run.

You can always use the Firebug extension for viewing headers too. HOWEVER, I am happy to see the extension being actively maintained too rocknbil ;)
