The link posted at http://blog.mozilla.com/devtools/2011/07/21/121/ to download the latest devtools build is 404'ing
It should be pointing to http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-fx-team/ these days.
Correct me if I'm wrong, but 13.0a1 is the "mainstream" Nightly - I was looking for the build that had the new dev tools. I have 13.0a1 installed and the dev tools appear to be the same as stable and aurora. Maybe I'm missing something?
I was just looking for the latest version of the dev-tools - I reported the issue because the 404'ing link is on a public facing blog
OK, I've updated the blog post to reflect that the best place to go right now to see the latest tools is Nightly.
