When is it coming?
If you are in a hurry, download the .xpi file to your desktop (save link as) and then using your .zip program of choice unzip the contents to a folder on your desktop, open install.rdf in your favorite text editor and scroll down to the line that says:
<em:maxVersion>3.6a1</em:maxVersion>
and change that to:
<em:maxVersion>3.6</em:maxVersion>
Then .zip it back up change it from whatever.zip to codeburner.xpi and then drag it into your open Firefox window.
Hope it helps.
Thank you very much!!
