  • all errors from the same FF 52 session (three year old browser) , does not seem relevant. Closing.

There were 37 errors in last 12hrs from 4 IPs While 4 of those came from Firefox 67 and 52, 33 came from 2 IPs using Firefox 79 a much more modern browser [1]. That said the errors are still low (for now) but I think it's wrong to dismiss this just on age.

https://bugzilla.mozilla.org/show_bug.cgi?id=1406348 might relate but it's an old closed bug, but it would be nice to say with certainty that this is not an error to be concerned about.
