For those who are wondering, I _think_ AMO is supposed to mean "addons.mozilla.org" although neither the author of the article nor this comment define the acronym.

I was also somehow aware of this acronym. Turns out the about page of Mozilla's add-ons page also uses it[1], so it's "official" so to speak.

Yes, indeed, AMO means addons.mozilla.org

The article currently does define it, but maybe that was changed.
