If this is meant to be a one stop shop for Mozilla projects and initiatives, where's Thunderbird, Monitor, and Relay?

I see two articles for Solo, but no links in the menu to anything but articles about: Firefox, Firefox AI, and Firefox VPN, articles on Anonym, and some various opinion peices...

Oh, yeah and one big Download Firefox as if that's the only thing they have for download.

They mention AI and some sort of consolidation but to me the blog entry seems to have little information. I clicked thru to the wiki entry also. Maybe someone that keeps up with this space could flesh out what are the actual implications?
