I decided not to install the add on nor use firefox relay, especially in the context in which the recomendation first appeared. I certainly do not want any facebook tracking, but i'm not sure the relay would work in the context , which was a prestablished identity on an energy website. But also I found the guidance and what-to-do, what-happens-next, was too hard to follow and left me baffled. I seem to have acquired an alias , but i'm not sure what to do with it. I seem to have logged into firefox, but I'm unsure what is involved. Will i be automatically logged into firefox when using it? I hope not. Can I log out? But nothing is clear. Since it seems almost anything on the internet is unhackable, I find myself uneasy about handing over yet more details to a database (i.e firefox's) that would be in itself a prime target, unless the benefits outweigh the risks.
