I'm listed as one of the owners of Slithering[1] and I didn't receive an email notifying me of the domain name change despite being affected. I found out the hard way when I couldn't install my app from the marketplace anymore and then got the misleading "INVALID_MANIFEST" error. Luckily I noticed the domain name change myself when logging into the marketplace on desktop and was able to quickly figure out the cause by reading the webapps code. Otherwise, this could have turned into a lengthy debugging session. See URL field for how the manifest looked before my fix. The app is only on https://marketplace.firefox.com (formerly https://marketplace.mozilla.org ) and not on any dev/test marketplace sites AFAIK. What site was the script run on? [1] https://marketplace.firefox.com/app/slithering/

Saw this also happen with Mixcloud as well. We need to clean this mess up.

I just received the email dated November 18, 2012 8:46 PM PST

There was a mistake in the actual line that sends emails so our testing didn't catch it. We fixed the problem and tweaked the email message to match our current scenario. As comment 2 mentions, email has gone out. On the bright side, we're in a simpler world now where authors don't have to juggle two domains. I changed the instructions to just replace the old with the new.
