Developer Edition aka Aurora was a development channel and was not versions or codenames of Firefox. It is currently only Release < Beta < Nightly channels.

You can look in https://archive.mozilla.org/pub/firefox/nightly/ then year folder the look around in month folder and the folders that mention aurora.

Thanks, so which folder means develop version?
when doing addon development, we need develop edition, otherwise, any minor changes need to sign.

I need to test something and need an older development edition version. Unfortunately, Mozilla has apparently pulled all old development edition downloads older than version 54:

Is there any way to get versions older than 54 or have they been obliterated from the Internet? I did try Google searching; I was not successful.
