Other interesting tidbits at about:about - reminds me of Portal:Portal - include:
about:compat (user-agent and CSS overrides for sites that hate foxes, and/or have terrible style - like Steam's community site, USPS, DirecTV, Lloyds Bank, Santander, Bank of America, Slack and, oddly enough, Zillow)
about:studies (tests being run live in production)
about:policies (turns out the administrator can control everything)
about:license (Firefox is licensed, not sold), and
about:telemetry (where you can see them watching)
about:support (lots of potentially-useful information)
There may not be lizards, but they do have robots, left over from Firefox 3.
You can see them if you use it and manually navigate to about:robots.

And of course, there's about:mozilla - which refers to the Beast, so there was one after all.
