Firefox is calling home when I starte it

now I understand about google search when I first start firefox on latest mx linux, but why in the world it is sending data to ?? and how can I check what is going w that?
I am emailing the maintainer at mx linx as well, but I just thought to give you folks heads up, and see what you say … The name and other stripe info flashes real fast on the bottom left when firefox starts, I am just surprised , since i installed this linux , I don’t think I have been to stripe’s site … What can I do to find out more info about this?

Hello Joao,

This doesn’t look like the right place to get answer, this channel is about Firefox developer tools.
