I'd prefer not to downgrade Firefox; I've encountered non-trivial
problems with my profile when I've done so in the past.

And when you said "Where are these showing up?", I thought you meant
"where on the web", which I answered; I didn't realize you meant "what
log".

They show up in Firefox's stdout or stderr.  Once upon a time they would
have ended up in .xsession-errors; now they end up in user.log and the
journal.

A quick search for "field value" and "selectedLogin value" shows other
reports of firefox producing this output.
