Apparently late last night Mozilla launched the new Add-Ons Manager (AOM) site or at least that is what Ryan at CyberNet News is saying. For reasons unknown at this time it seems Mozilla has reverted back to the original AOM. Of course there are several theories as to why this may have happened from missing add-ons, broken links and issues with the sandbox (the place where unapproved extensions are kept). So it looks like we will have to wait a little longer for the new and (some what) improved AOM site.
