From what I can tell, the “Ubuntu Mozilla Team” does not consist of people from Mozilla but rather just people packaging Mozilla software for Ubuntu. The latest packages in that PPA have been uploaded by Rico Tzschichholz, who does not appear to be affiliated with Mozilla.

Kudos to open source maintainers, the hidden heroes who make your life easier while expecting nothing in return.

This is confusing because it’s posted on Mozilla’s official site

The thing posted on Mozilla's website (the OP) is official. The PPA posted at the root of this comment thread isn't.

Get rid of your PPA package and use the official repo, it's 99.9% better in almost all cases. More details on google/youtube on how to do that, it's too much to type on HN and should be on the first page of google/duckduckgo. I would guess the people supporting the PPA will stop updating it after a while due to there being an official repo to use.
